"Software development is dead" they said.
Last month a client paid me $20,000 for an app. My cost was $200 for Claude Code.
It's a kiosk mode app for android tablets in taxis. Ads for partner companies, tipping the driver, admin, backend, the whole thing. Now live in production.
I didn't write a single line of code. Still took 1 month of constant work.
The best part? The client came to me with a vibecoded version first. It was horrendous.
He paid $20k because he needed someone who has done this before, professional design, real assurance, and 12 months of support.
You can't vibe code that.
Without AI it would have taken 3 months and cost him 2-3x more.
Developers using AI will always win. Stop listening to people who say software is dead for views.

The biggest psyop in Bitcoin isn't a scam or a hack. It's the narrative that you need a hardware wallet to keep your Bitcoin safe. That's complete bullshit. You don't need keys on any wallet if you're not spending not on your phone, not on a computer, not on a hardware wallet.
All you need is a watch only wallet. The private key is a spending tool, not a holding tool. This is why EntropyLab exists.
EntropyLab’s first release candidate, v1.0.0rc1, is here. 🪨

Look at the chart below. Most people scroll right past it because “bond yields” sound like something only bankers care about. But you should care also as the bond market is telling you the entire Western financial system is starting to break in real time.
- Quick explanation for the lay person: A government bond is just an IOU. When you buy a 10-year bond, you’re lending the government money for 10 years. The “yield” is the interest rate they have to pay you to borrow that money.
- When yields go UP, two things happen at once:
The government has to pay a lot more interest on every new dollar/yen/euro it borrows.
- All the old bonds that already exist become worth less, because nobody wants the old cheap interest when they can get higher interest now.
Now look at the numbers:
- Japan’s 10-year yield has jumped 49% just this year. Their 2-year and 5-year just hit 31-year highs. Japan is the most indebted major country on Earth. They owe more than twice their entire economy. For decades the Bank of Japan printed money like it was going out of style and forced yields down near zero so the government could keep borrowing cheap. That game is over. The market is now saying “we don’t believe you anymore.”
- France +32%. Italy +29%. Germany +24%. The US +23%. Britain +20%. These aren’t small moves. These are the bond markets of the "richest" countries on the planet starting to revolt.
- China is the only one going the other way. That’s not because China is a genius. It’s because they have capital controls and a completely different system. They don’t play by the same “free market” rules the West pretends to play by.
Here’s the part they will never tell you on CNBC or Bloomberg or Handelsblatt:
- These governments cannot pay this debt back with real money. They never intended to. The plan was always to print the difference and hope you didn’t notice your grocery bill going up. That’s why they spent 15 years keeping interest rates at zero. Zero rates = cheap debt = they think they can kick the can forever.
- The can just hit the wall. If they let rates stay this high, interest payments will eat entire budgets. In the US, interest is already more expensive than the defense budget. In Japan it’s even worse relative to the size of their economy. They will not cut spending., EVER! Politicians never do once they taste the printing press. So they will print more. They will call it “quantitative easing” or “yield curve control” or “Treasury twist” or whatever new name they invent. Same thing: they create money out of thin air to buy their own bonds so yields don’t go even higher.
- That newly printed money doesn’t stay in the bond market. It leaks into everything you buy. Food, rent, cars, energy. That’s inflation. That’s why your paycheck buys less every year even when they tell you inflation is “under control.”
- This is the same movie we’ve been watching since 1971 when Nixon closed the gold window and the US dollar became pure paper no longer backed by gold. The United States, as issuer of the world reserve currency, got to print and force the rest of the world to eat the inflation. Japan, Europe, and the rest copied the model. Now the bill is coming due all at once.
- They will not default. Default is politically impossible. They will inflate the debt away. That means the paper in your bank account, your pension, your government bonds ... all of it ... will buy less and less.
- The only assets that cannot be printed are gold and silver, land as well. That’s why central banks have been buying gold hand over fist for three years while they tell you everything is fine.
- This chart isn’t “interesting market data.” It’s the sound of the fiat system groaning, creaking like the Titantic before it broke in half. Japan is just the first one the market decided to slap in the face. The rest of the West is next.
- We need an incremental return to some type of hard money standard, it's the only way. Until then, this is the path: higher yields ... more printing ... more inflation ... poorer people.
We're all screwed together. So plan accordingly.
A quick endnote ... there is one major nation unaffected by all of this. The name of the country starts with an R and ends with an A. Clues: Not Romania and not Rwanda. And a certain leader, his name begins with a P and ends with an N, he sees it coming too and is sticking and moving, playing for time. If he can hold out long enough, the world may just have a chance for real change.

If only we could ask Alan Greenspan about how to deal with this debt problem.
Oh wait, Greenspan warned about this 20 years ago & 10 years ago, concluding, "Unfortunately, I don't see how we're going to get out of this before we have a crisis."
PS: Jamie Dimon agreed with him👇

I view Bitcoin as a game theory problem where the cost of ignoring it rises as adoption increases.
I do not need everyone to believe in Bitcoin.
We only need enough rational actors to realize that if Bitcoin continues monetizing, owning zero becomes the more aggressive position.
I think about it like a coordination game.
At first, Bitcoin looks optional.
But every new participant changes the incentives for everyone else.
When an individual buys Bitcoin, almost nothing changes.
When millions of individuals buy it, institutions start paying attention.
When institutions allocate capital, competitors have to explain why they own none.
When corporations hold Bitcoin, other treasury teams have to evaluate the opportunity cost of sitting entirely in fiat assets.
When sovereign entities accumulate it, other governments have to consider whether remaining at zero creates strategic exposure.
That is where the game changes.
I believe Bitcoin becomes stronger precisely because nobody wants to be the last rational actor to recognize a scarce monetary asset.
If I believe there is even a meaningful probability that Bitcoin becomes a larger global reserve asset, treasury asset, settlement asset, or long-term store of value, then I have to ask myself a different question:
What is the risk of owning none?
That is the part of Bitcoin game theory
I think many people underestimate.
My framing is that, once adoption reaches sufficient scale (we are here), having zero exposure becomes the major risk.
WATCH!

people who stored their btc on coldcard got drained because of entropy.
the seed generation was reproducible, anyone could recompute their keys.
so i went through every other hardware wallet to see how they make your seed, and whether the same thing can happen again.
@Trezor: mixes the device's randomness with randomness from your computer, and the device has to prove it used both. even if its chip is fully broken, you're still fine. the best design here by far.
@BitBoxSwiss: 5 separate sources of randomness combined. one bad source can't sink you. open source, reproducible builds, dice supported.
@FoundationHQ: built their own randomness circuit out of plain resistors and capacitors, open source, on top of two other sources. no black-box chip to trust. supports dice.
@KeystoneWallet: 2 secure chips from 2 different manufacturers, combined. also lets you roll 99 dice and publishes how to check the result yourself.
@Blockstream: jade pulls from 7 things: radio noise, cpu counters, battery, temperature, camera, your input, the app. very hard to break all of them.
@SeedSigner: your dice are the only source. no chip to trust at all. and they ship a guide teaching you to verify their own math. weakest hardware, strongest proof.
@OneKey: secure element plus mcu combined on device, open source firmware. solid, but you can't add your own randomness.
@Ledger: one certified chip (AIS-31, EAL5+). good randomness. but it's a single source, closed source, and you cannot verify any of it. you're trusting them completely.
@Tangem: key is born inside the chip and never comes out. audited by three firms. same trade: strong, and impossible for you to check by design.
@ngrave_official: mixes chip randomness with your fingerprint and room light. clever. but the "EAL7" badge covers one software component, not the whole device.
@ELLIPAL: single certified chip, no software fallback, fails closed instead of guessing. closed source, so take it on faith.
@SafePal: 2 chips mixed. they've never published the details.
@COLDCARDwallet: patched now, and dice on coldcard were always verifiable. but every seed made between 2021 and 2026 is permanently burned.
one source = ledger, tangem, ellipal. that one source fails, everything fails. their answer is to make it excellent and certified. that's exactly the bet coldcard lost.
many sources = trezor, bitbox, passport, jade, keystone. one broken source never reaches your key.
and every one of these claims 128 or 256 bits.
coldcard did too. certification doesn't help either, coldcard's chip was fine, the code just stopped calling it.
the only thing that saves you is being able to check.
roll your own dice. verify the words yourself.

🇯🇲 Marquin 🇵🇸 retweeted
IMPORTANT SECURITY UPDATE:
COLDCARD users who relied solely on device-generated randomness may be at risk from a security vulnerability that may steal your coins.
Users who followed best practices and generated their seed with 100 fair, independent, and private dice rolls are not considered at risk. 50+ rolls seems to also be safe.
If you generated your seed on a coldcard without 100 dice rolls, you should:
1. Generate a completely new seed on an unaffected device or airgapped computer.
2. Carefully record and verify the new backup.
3. Verify the wallet fingerprint and receiving address on the hardware wallet.
4. Send a small test transaction.
5. Confirm that everything works before moving the remaining funds.
Alternatively, and if any of this is confusing or feels uncertain, move your funds to an exchange custodian temporarily while you figure out how to set up a new seed safely.
Anyone uncertain about the firmware used, the number of dice rolls, or whether those rolls remained private should assume the seed may be affected and migrate.
The bug prevented the hardware random-number generator from contributing the intended amount of entropy during seed generation, substantially reducing the effective seed-search space. It is not a bug in bitcoin and it doesn't affect any wallets not using coldcard firmware.
A strong, unique BIP-39 passphrase adds an independent security barrier, but the protection depends entirely on the strength and secrecy of that passphrase. Even users with a strong passphrase should migrate to a newly generated seed as soon as practical.
Never enter your seed words or passphrase into a website, computer, phone, chatbot, or “recovery service.” Do not panic, but do not ignore this. Proceed calmly, verify every step, and act promptly. For further updates, rely on official Coinkite and COLDCARD sources:
• Security announcements: blog.coinkite.com/
• COLDCARD on X: @COLDCARDwallet
• Coinkite on X: @Coinkite
• Firmware releases and upgrade instructions: coldcard.com/docs/upgrade/
Be cautious of unsolicited messages, unofficial “recovery tools,” and accounts offering to help migrate your funds.

I spent time in Shenzhen last year and when I saw Merz come back from China saying Germans need to work more I immediately knew what broke his brain because I lived the exact same cognitive shock
my first week in Huaqiangbei I burned through 4 prototype iterations of a motor controller board for less than a thousand bucks total, back home a friend was working on something similar and spent over 12 thousand for a single revision that took almost two months to arrive
when you live that contrast in your own hands with your own project something permanently shifts in how you see the world and it goes way deeper than speed & cost
what Shenzhen actually built is a collective learning organism, imagine 20 PCB fabs 15 injection mold shops 30 component distributors and a hundred firmware freelancers all within a 2km radius, looks insanely redundant from the outside until you realize redundancy is actually information density in disguise
I watched this firsthand with an injection mold supplier I was working with, this guy had seen a hundred founders iterate similar thermal designs over 6 months so he proactively modified his tooling before I even opened my mouth, he knew what I needed before I knew what I needed, the intelligence lives in the relationships between the nodes and it compounds daily
the west thinks about manufacturing as a cost center you optimize by centralizing…
China accidentally built a distributed neural network of manufacturing intelligence where knowledge diffuses horizontally across thousands of agents faster than any single western company can process internally
so when Merz comes back and says we need to work a bit more I think he saw the problem but COMPLETELY misdiagnosed the solution, telling Germans to work harder is like telling a horse to gallop faster when the other side built a combustion engine
the gap is ARCHITECTURAL
it’s ecosystem density, you need a custom connector in Shenzhen you walk 200 meters, in Munich you send an email and wait 3 weeks
it’s iteration speed, parallel search vs sequential optimization at the system level, it’s risk tolerance, Chinese founders ship something broken on Monday fix it Tuesday ship again Wednesday while European companies are still in the approval phase for the pilot program of the feasibility study…
and Merz only saw the surface, what he missed is the tier 2 cities like Hefei Chengdu Wuhan replicating the Shenzhen model at scale right now
BYD going from irrelevant to outselling every european automaker combined in roughly 5 years, Huawei building its own 7nm chip under maximum sanctions when every analyst said it was physically impossible & behind all of that a government that treats advanced manufacturing as an existential national priority while europe debates whether AI needs another ethics committee
I think what we’re watching is the most asymmetric economic competition in modern history and most western leaders are still framing it as a productivity problem when it’s actually an ontological one
Europe & America are optimizing variables that China stopped tracking years ago meanwhile China is compounding on dimensions the west has no framework to even measure
Merz at least had the courage to name
it out loud and I respect that genuinely but working a bit more inside a broken architecture just means you arrive at the wrong destination slightly faster
NEW:
🇩🇪🇨🇳 German Chancellor Merz says Germans need to work more in order to match China:
“We are simply no longer productive enough. Each individual may say, “I already do quite a lot.” And that may be true.
But when you return from China, ladies and gentlemen, you see things more clearly.
With work-life balance and a four-day week, long-term prosperity in our country cannot be maintained. We will simply have to do a bit more.”
