Dear Home Owner,
I want you to pause a little before you build.
The pause can be 1 hour before ground breaking or one week before you sign that contract.
Take a moment.
What if there is a chance you can build a more beautiful, functional and timeless houseβ¦
On the same budget?

Preparing for a case and its interesting how the colonial government surveyors had noted that Lake Naivasha levels go up and down and had marked the contour below which all that land should be considered riparian land.

Collect the houses you could really build.
Pin the designs you would actually build to your own profile: costed, local, buildable.
Curate your future, not just your feed.

There is no guarantee of electing good* leaders.
I think we should strengthen exits.
The only guarantee is strong working institutions iThink.

Quantifying the Future
This is what a $2 trillion economy will look like by 2040β¦
+ 1x port facility with 3x8km lay down area
+ 1x robot fab plant producing 100 bots / hr
+ 1x 1GW datacenter running inference
+ 1x 3GW nuclear power station
= 2 million robots labouring 24/7
We know enough today to model the thermodynamics and the market economics of such a site already. The numbers above are the ballpark numbers you end up with, feel free to challenge or change for your own assumptions.
Embodiment is the ceiling for both the thermodynamics and economics, as compute (and intelligence) pretty much trends towards zero under Mooreβs Law.
Assuming a robot is 500W of Newtonian motion, as humanoids are, then 2,000,000 robots working 24/7 is 1GW of demand for the robotsβ actuators.
Letβs also assume a 1GW datacenter is required for inference for 2m robots, supervised by a central monolithic superintelligence. Thatβs 2GW total.
Then for the sack of maintenance and replacement, we assume 500MW robot fab can produce 100 robots an hour (only ~ 5 ton of product / hr, below a car plant, but includes chips). Thatβs now 2.5GW site total.
For 2,000,000 robots to create $2T of value, each bot needs to add $1m of value each year
Seems a lot, but each robot is assumed to work 24/7 and only last ~2 years before it is defunct.
24x365 =8,760 hrs/yr
=>$114/hr
Seems high at first, but this is a hyper collaborative hive mind marshalled by 2040 superintelligence. $114/hr is what you pay for a car mechanic in 2026, and we are using 2026 dollars here.
We can even look at the thermo and economic density and the total footprint of this economy is just tiny.
3x8km is 24km^2 (about 6,000 acres).
= 83,000 robots / km^2 = 12m^2 per robot
Thermal dissipation
= 500W / 12m^2
= 41.7W/m^2 (just 2-3% of solar insolence)
Value add density
=$1m / 12m^2
=$83k / m^2 <- Wow!!
This is $2T GDP from just 8km of coastline
Or $500bn of GDP per km of dockside
The entire economy can be compressed into the 3km deep dockyard behind the dockside.
Thatβs an economy the size of Australia or Mexico in a land area the size of San Francisco Airport.
This is absolutely where the future economy is going, nothing can compete with the capital efficiency of this setup. Nothing.
Docks are also crucial as itβs simply not possible to handle the prerequisite volume of cargo and goods for such an economy using anything other than isomodal freight handling systems.
If your nation state is interested in adding $2 trillion to its tax base⦠my DMs are open.

Replying to @NafunaOkemwa
He who tickles a mad woman in the night should not act surprise when the mad woman tickles him on a market day.
An exercise in incorrigible incoherence.
Gladys Boss: The National Assembly deleted clause 22 which retained section 39 as per the judgement of the court
Gituku: Are you aware that there is a court of Appeal decision that found section 39 unconstitutional in 2023? So the National Assembly is retaining a section that is already unconstitutional?
Gladys Boss: What we should be asking ourselves is if there is a problem we could go back to the process and remove the livestreaming #CitizenDayBreak

I love working with fundis. Their experience is real, and many rules of thumb are good.
But I always check them:
1. Does this match the drawings?
2. Does the engineer agree on sizes, spacing and steel?
3. Has it been measured on site, not guessed?
4. If it differs, who approves the change?
Asking is not an insult. It protects the fundi and you.
Start with a clear design on podcity.ke, so everyone builds from the same drawings.

Most people talk about their dream home for years. Few ever see it take shape.
PoDCity changes that by letting you explore real designs, calculate accurate costs, and lock in your ownership goal in one place.
No more scattered ideas. No more guessing what it will cost.
Ready to move from intention to plan?

"Low maintenance."
I hear it from suppliers all the time. Fine, but show me.
When someone sells you a finish, a roofing sheet or a paint, ask:
1. Do you have test results?
2. Can I contact a client who has used it for a few years?
3. Can I visit a building where it has been in the rain and sun?
4. What does the warranty cover, in writing?
A nice testimonial is not proof. A product that has stood up to our weather is.
Choose your design and style first on podcity.ke, then ask for proof on every material you put in it.

The factory of the future will have only two employees, a man and a dog.
The man will be there to feed the dog.
The dog will be there to keep the man from touching the equipment.
