I don’t think anyone was under any illusions. Britain didn’t have a choice or any leverage. It was a 99 year lease so there was no legal claim to keep HK and the UK wasn’t going to war with modern China. China could have just taken it if Britain set a bunch of terms.
Before the handover, they just basically offered Hong Kong residents the right to move to England. Canada, Australia, and the U.S. had special rules for immigrants from HK. (Probably other countries too.)
Yeah, right. He resigned because they raised $100m and was burning through at least $8m a month. A bunch of staff left and he failed to commercialize or find a partner with deep pockets — like OpenAI with Microsoft — to lower costs. (OpenAI gets a ton of compute credits from Microsoft). Whatever the technical merits of stability AI is, it’s a shitty business.
And that’s just what’s public info. He probably was offered the opportunity to resign or be fired by their board.
