Self-driving has different economics. We're reading tea leaves, true, but it's also true that software has zero marginal cost and that $20K pays for an engineer-month in SF.

Do you have a hard spec and rock-solid test cases? If you do, you have two options to a working prototype: 2-6 engineer-years, or $20K. The second option will greatly increase in quality and likely decrease in price over the next few years.
What if the spec and the test cases are the new software? Assembly programmers used to make an argument against compiled code that's somewhat parallel to yours: every instruction is a (performance) liability.

There will be humans, just fewer and fewer. The spec and test cases are AI-eligible too.
> safe, secure, and compliant software
I'm not sure humans' advantage here is safe, if it even exists still.
