tweeting as a founder used to be a negative signal. now going direct is table stakes. in a world where anyone can build software in plain english and the cost of execution is being driven down to zero, distribution becomes the only moat.

AI makes software development ~2x faster. yet our products aren't evolving 2x as fast. updates aren't arriving 2x as often. where is all this productivity going?.

lots of fun building with the latest and greatest: a little help from @cursor_ai (ok, a lot), @vercel for making deployment really easy, claude 3.5, and a fair bit of old fashioned artisanal hand coding.

.@sama was the first person to invest in and believe in us at @Codecademy. he’s been an inspiration and driving force behind many founders since then and went on to change the world with openAI. rooting for his success.

I stand with Israel in the fight against terrorism and the slaughter of innocent civilians. Hamas’ terrible terrorist attack on innocent civilians is despicable and gut wrenching.
