I don't think it is unreasonable to ask where all the great AI built software is. There has been comments here on HN about people becoming 30 to 50 times more productive than before.
To put a statement like that into perspective (50 times more productive): The first week of the year about as much was accomplished as the whole previous year put together.
I haven't made any "great" software ever in my life. With AI or without.
But with AI assistance I've made SO MANY "useful", "handy" and "nifty" tools that I would've never bothered to spend the time on.
Like just last night I had Claude make a shell script on a whim that lets me use fzf to choose a running tmux session - with a preview of what the session's screen looks like.
Could I make it by hand? Yep. Would I have bothered? Most likely no.
Now it got done and iterated on my second monitor while I was watching 21 Bridges on my main monitor and eating snacks. (Chadwick Boseman was great in it)
I'd question your assumption that the software would be "great". I think we're seeing the volume of software increase faster than before. The average quality of the total volume of software will almost certainly decrease. It's not a contradiction for productivity in that respect to increase while quality decreases.
I'm honestly not a big fan of when people throw out numbers implying a high degree of rigor without actually showing me evidence so I can judge for myself. If you're this much more productive, then use some % of that newly discovered productivity to show us.
But building software does tend to come with a lag even with AI. And we're also just more likely to see its influence in existing software first.
I'd rather be asking where it is AND actively trying to explore this space so I have a better grasp of the engineering challenges. I think there's just too many interesting things happening to be able to just wave it off.
