AI Progress From Autocomplete to Compilers: Software Abundance Vision
By
–
I think this group of reactions are still fundamentally rooted in a scarcity mindset of software. 2 years ago AI was botching autocomplete, today it is almost one shotting browsers and C compilers. Where is it in 2 more? 10? 20? Software so insanely cheap and abundant that
