If there's one current technology that I wouldn't call omakase, it would be React. I thought it would get better once redux reached a certain mindshare, but now there's a plethora of redux helpers, "best" practices etc. (Each of which seems to focus on a new and/or experimental JavaScript language feature)

Hey, I program Perl in my day job, but this is way too much Tim Toady even for me.

(And if "more money" were the only reason for technology adoption, there's probably more to be made in Enterprise Java development, at least on average)
