Best money I've ever spent as a CEO... an internal AI transformation hire. He doesn't care about title. He just wants to ship. And he goes across your entire org, sales, revenue, hr, apps, tech and kills stupid manual processes. Such an underrated unlock.

GPT is obedient and will follow your detailed specs, while Claude allows for vagueness Original tweet: https://x.com/xeophon/status/2011359688387076242
Did some statistics. My productivity ~doubled with moving from Claude Code to codex. Took me a bit to figure out at first but then 💥

I have lived in San Francisco for 22 years now. The best way to get a sense for how good/bad the city is doing is to just take a long walk. Through the TL. Through Civic Center/Mission/Van Ness/Market. I do this every 3-4 months. Some recent thoughts: - TL feels cleaner. -

RT nexxel Re to be clear, huge respect for claude code and opus 4.5 is incredible. you all pioneered this space. but the auth change today is rough. this worked yesterday. people built workflows around using their max subscription with tools like opencode, and now that’s just gone. and honestly once you’ve set up a custom opencode workflow with your own tools, your own context, your own memory integrations… going back to claude code just feels like a downgrade. it’s slower, more bloated, and you lose all the customization that made the experience actually work for you. it’s not that claude code is bad as a starting point. it’s that actively removing functionality that paying subscribers relied on feels like the wrong move. if claude code is the better experience, people will migrate naturally. you don’t need to force it. taking away something that worked and was valuable to power users just damages trust. and power users tend to be your loudest advocates. would genuinely love to understand the reasoning here because from the outside it just reads as lock-in over competition. ps: big fan of your work!! you’re a huge inspiration Original tweet: https://x.com/nexxeln/status/2009601024127045766

Trials and tribulations of being an indie consultant. One of my friends submitted an invoice, and someone on their team replied, "Blocked. I caught you scammer" and denied the invoice. It took them a whole day for them to realize this and forward it back to the CEO. The CEO has been very apologetic.
