I might get downvoted for saying so, but the internet is a dangerous place. If you aren’t alert enough to solve a captcha, much worse things can happen to you than having difficulty signing into GitHub. I’d prefer GitHub to remain secure, even if it’s hard for a negligible fraction of users who forget their passwords.
I don’t find it particularly so. I sort of like that style captcha as it requires thought. One has to figure out to quickly estimate and not actually try to sum/count the exact numbers. Maybe you have to do it twice, but it’s not very hard for a lot of people, obviously or it wouldn’t be deployed in production.
