Current models aren't capable of that, but that doesn't mean it's not possible.
If you made models able to code to long spec, you would be left with the hard issue of having to write them.
Like if you show the LLM a page, can the LLM review the page and then spit out a review that is close to what a human would say about the page?
Software was always that way, though.
> given the sufficiently smart compiler
For those unaware, this is a similar quote used by compiler proponents. The first full compiler was created in 1957 (+/- 70 years ago) and the "sufficiently smart compiler" never happened, hand written code from the best coders still is faster. Now, that doesn't mean that compilers didn't do the job well enough, we just accepted that 90-95% of the top speed was enough for almost everything.
To the LLM one shotting point, it took 30 (40?) years for compilers to be good enough for the mass market. Caveat early adopter and investor.
Plus what pyrale said.
