I believe you are underestimating the value of GCC and LLVM having won the compiler wars and being extremely high quality, and of Linux having won the OS wars, being extremely high quality. I use GenAI every day, but the quality is still proportional to the amount of my time - there is a multiplier for quantity of my amount but the 9s approaching 1 quality is not logarithmically different - the effort to fix one big is lower, but the total effort to make excellent software is still a process of polishing and then iterating. The embedded quality in GCC will take a similar order of magnitude investment from an LLM rewrite. These super high quality open foundations make LLMs more useful to us now, but saying that the embedded value or cost of GCC or Linux is zero I think will steer people wrong.
