It would certainly be an accelerator for people who know exactly what they want. And it would remove multi tasking, which I‘d appreciate.
This is the "dumber but honest person that works harder" phenomenon, vs "lazy genius".
Sure, in the future full rewrites and stuff like that will be just another "throw money at it" problem, but fundamentally software can get arbitrary complex and we barely know how to write large, maintainable code bases.
Nonetheless, I think testing (and maybe proofs) will have its long-awaited time to shine, as being the "reward function".
Right now, I put models in low thinking mode during my refactors and hate waiting. I would much rather have a faster model that that maybe was slightly stupider, and I would wait far less long between prompts where it needs my valuable input.
Models that are dumb, but humble and fast, can be fine.
Obviously a CTO is not going to walk away from the technology just because it's not good enough. That much more incentive for someone to create a powerful enough harness that can direct that power safely and productively. Like a nuclear core, we'll need to come up with the graphite rods and water tank. And if tokens are essentially free, why not, for every million tokens, spend 10x tokens on code review, testing, etc?
