Their shitty UI is also not doing them any infrastructure favors, during load it'll straight up write 90% of an answer, and then suddenly cancel and delete the whole thing, so you have to start over and waste time generating the entire answer again instead of just continuing for a few more sentences. It's like a DDOS attack where everyone gets preempted and immediately starts refreshing.

Yes! It's infuriating when Claude stops generating mid response and deletes the whole thread/conversation. Not only you lose what it has generated so far, which would've been at least somewhat useful, but you also lose the prompt you wrote, which could've taken you some effort to write.
