I wrote about AI and programming.
About the identity challenges we are facing as programmers and the potential erasure of craft.
There's a fun little easter egg in the header as well :)

Quilicura, Chile, one of the communities I wrote about in EMPIRE OF AI, has launched a brilliant initiative to inspire more responsible AI prompting. Today, don't use AI; ask the townspeople instead: quili.ai. So heartened to see this creative act of resistance.
