So we're not actually much faster at the core code, because reviews still take time. Ultimately, we're on the finance markets and we have regulatory pressures and I, as the human, am responsible for putting the code out there.
But we're freeing up a lot of time to get other things correct. We have n x more metrics now because plumbing in basic stuff is now trivial. We now have dozens more tools and skills to help analyse issues (e.g. why this price and not x), answer questions, etc.
I now have skills to scrape logs, download unpack and scape our bus persistence, link to kdb, and so on, all in my claude prompt, joining it all together and the AI is figuring things out. I can diagnose things, I don't know, maybe 100 times faster?
It is revolutionary, and I am highly sceptical of the motivations of people who keep saying otherwise.
