I mean sure, if it was my full-time job to write regexes I’d probably get pretty good at it. But instead a really complex one comes up maybe once a year for me and so I have to go to some online regex checker and start iteratively building one up, spending hours only find some condition where it doesn’t work and back to the checker... So I don’t think it’s easy, but I do agree that they are very useful.
