Sometimes I wish our language had tenses or other markers for levels of epistemic confidence. A one-syllable way to say: "I believe X because I have mathematical proof" "I'm underqualified on this topic, but my feeling is X" "My impression from observations so far is X" etc

Let's talk about the real source of centralization on the beacon chain. 1. Solo staking is still too challenging for most. 2. Decentralized staking options feel risky to most. 3. Giving money to a third party for staking is just easy and people know how to do that.

It was sickening when video game retail went from $40 -> $60 Now it costs $5k+ for one individual character in a game that may or may not be in development with a team that may or may not be two 12 y/o coding in the basement
