In every regime where we have meaningful longitudinal data about the long run outcomes of introducing technology that is superhuman at some or all of a human's job, the combination of the machine and an expert human outperforms either alone, with probably the clearest parallel structurally being chess, though this is true of all of the hard sciences and all of frontier engineering (semiconductor design).

There will never be a human who can beat Stockfish ever again, digital intelligence has simply accelerated away from human intelligence in that regime.

There is no other human alive who can beat Magnus Carlsen. Stockfish crushes Magnus.

But Magnus and Stockfish playing together crush any conceivable combination of just human or just computer. And no serious chess player would train without a computer or decline the assist if the contest mattered.

And this is in a regime where the dominance of the machine is total, structural, and permanent, far more so than any existing AI's impact on the outcome distribution of any recent development on any white-collar knowledge work include even the most sophisticated software engineering done anywhere. The demonstrated as opposed to completely conjectural lift on SWE outcomes with Claude Code (and even that's controversial, let's take the high end of the claims) is real and changes the geometry of the situation not at all.

Nor is there any apparent limit on how much arbitrarily sophisticated software the world has an appetite for, you could take someone at the absolute top of the field (I'm a big Carmack fan let's go with Carmack), and give him cutting edge AI assist, and the best program a person can write just got better. Sweet!

And this applies anywhere from junior to Carmack: however good they were, they're better now. We can build harder things. We can have extreme quality software where previously we were stuck with some Electron jank, across the board. Does anyone think Slack would lose market share if it went back to its gaming roots and was gorgeously 3D accelerated on every surface against a backend that could instant and perfectly synchronize an arbitrary workspace on a flakey cell connection and never have an outage or data loss? Or would they rapidly shred the remaining competition and become the favored tool of everyone?

In adversarial regimes like trading or drone warfare, you better believe the best hackers have arbitrary assist if you're going to play against them.

I think the thing to be hand-wringing about isn't AI, it's that capitalism no longer seems to be an adversarial regime. The worst software rivalries in the industry look more like a pillow fight than a battle of will.

And if there is any lasting reduction in headcount, it's leaders lacking ambition agreeing tacitly to not play very hard, not AI, that is to blame for that. None of the HFT shops nor amusingly the frontier labs have reduced their hiring or compensation at all. If anything, it's going up!
