Arrogant and condescending don’t mean “wrong”. Djikstra (the king of accusations of arrogance), once pointed out that his native language has no word for “egghead”: https://www.cs.utexas.edu/users/EWD/transcriptions/EWD12xx/E..., principally because his native culture has no history of dismissing the educated. OP is using (I interpret) “bootcamp data scientists” as a shorthand for people who know far less than they think they do. That seems like a fair characterization, honestly: that’s entirely the philosophy behind bootcamps in the first place.
The idea behind them is that a four-year education in computer science is unnecessary for routine software development jobs, and one can be trained up to useful programming ability in a much shorter time (and less cost) than a full-blown university education takes. While it’s difficult to say how true this is, OP (I interpret) and I have both observed that bootcamp types seem to presume that a few-month intensive bootcamp experience actually does cover everything that a four-year degree does, and are often surprised (as well as defensive) when they come across something that their bootcamp didn’t prepare them for.
A close analogue would be a paralegal thinking they know the law better than lawyers or nurses thinking they know medicine better than doctors - not that they don’t know a lot, but there are a few things that, while not as commonly useful, do come up in actual practice that are important when they do.
