The prediction that 90% of code will be AI-written by the end of 2025 deserves skepticism, though manual programming may yet become a horse: ridden for love, not transport.

What these subjects mean

AI and human skill Practised abilities decaying because a machine now does them: writing, thinking, reading anything long.

code generation Machines emitting code and files, and whether the volume they produce is a cost somebody eventually pays.

AI writing Prose a model wrote: what gives it away, what it does to reading, and whether anyone should publish it.

What David Heinemeier Hansson actually said

Do you hold this korrent?Do you also believe this?

In tension with

The metric that matters is engineering velocity, not the share of code AI writes, and at Google AI has raised it by about ten percent.

Pichai says the metric that matters is engineering velocity rather than the share of code AI writes, and puts Google gain at about ten percent. Hansson says the prediction that 90% of code would be AI-written by the end of 2025 deserves skepticism. They are arguing about the same number from opposite ends: one says it is the wrong number, the other that it is the wrong answer.

Shared subject first, then similar wording. They may agree or disagree.
