i don't know - I agree we haven't seen changes to our built environment, but as for an "explosion of new start-ups, products" we sort of are seeing that?

I see new AI assisted products everyday, and a lot of them have real usage. Beyond the code-assistants/gen companies which are very real examples, here's an anecdote.

I was thinking of writing a new story, and found http://sudowrite.com/ via an ad, an ai assistant for helping you write, its already used by a ton of journalists and serious writers, and am trying it out.

Then i wanted to plan a trip - tried google but saw nothing useful, and then asked chatgpt and now have a clear plan

very cool - what was the hardest part of building this?
