That's the comment you should have responded with instead of the one that you did.

Upthread used the term "tech" when the thread is very clearly talking about AI. AI is software, but because they used the term "tech" you cherry-picked non-software tech as a counter example. It doesn't fit because the type of tech that GPT-4 represents doesn't have the manufacturing cost like a chip fab does. It's totally different in kind regardless of the fact that they're both termed "tech".
