One good way to think about AI—and all major tech movements like electrification, the internet, etc—is as a Technological Weather Event.
Not just to say that it’s mostly unavoidable, but that it really matters how we think about and prepare for them as a population.

You don’t have to believe that companies want to fire all their employees to see AI’s threat to jobs.
That’s negative framing. Most company leaders are regular, decent people who generally care about others.

Our jobs mentality is based on a lie.
➡️ We were told that there are special people who make things—but we're not one of them.
➡️ And our role is to work for one of them, hopefully…
Fuck that. The illusion is collapsing.
You are the special person.
You can make things.

I’ve been thinking about how AI might reshape what it means to be a developer.
We’re hearing a lot of predictions—some saying tech jobs will vanish, others saying AI will supercharge demand. But I think the more interesting shift is in who companies will need.
