My guess is about 5 years till most startups use an LLM type copilot, 10 years for legacy companies, and then another 10 years after that for the ones that prefer older processes (think companies that avoided cloud etc). When the internet became widely available you had a good long while where many people refused to use it because it was different from what they were used to. LLM's are already on the same arc, and you can already get internet like gains out of using them today. Even after that I suspect a little code will be written by hand. The equivalent of writing assembly or C today. With how fast the LLM tech is moving though that may be naive.
