Luckily I dodged the flash bullet. When I got my first programming job in 2010 and was still full of imposter syndrome trying to pick up the previous devs Ruby projects (also hate) my bosses wanted a second dev and asked my to talk to a candidate they really liked. He had a master's degree in cs and I was just self-taught. Guy only knew flash that was it. Just starting out after college and he had a master's degree in flash development.
I wrote a very long heartfelt email to my bosses saying that I would basically hate working with him and that flash was such a stupid technology that it would probably die in a few years. How wrong I was. Apple killed it a month later by dropping support on iOS and Safari. I often wonder what happened to that poor candidate and if he could get the money back that he paid for his degree.
