We will look back on our use of AI generated art as blog banners and in slide decks with a mixture of nostalgia and cringe, like we do with myspace. Soon they will just look like professionally generated layouts so enjoy it.

I love using agents for analyzing codebases for me. My prior pattern of `grep` and manual skimming has been fully replaced with agents. I ask it to list sources and line numbers and then I go in and verify for myself (never blind trust). Examples: - https://t.co/6RpH9eo7wU -

@Devon_Eriksen_ I cannot agree with your dismissal of LLMs as nothingburgers. Yes they have serious limitations. No, they are not AGI. But they are in some significant cases, effective amplifiers of human intelligence. I'm going to talk about what I know. I've been a software engineer for a
