More frustratingly, at least for me, is that some of us have been warning about these things for absolutely years without many paying any mind, only for them to keep in happening again. Eg. https://news.ycombinator.com/item?id=16090120
I've found that some people tend to take a ton of pride in the assumption that they have to make mistakes to learn from them, but you almost always want to learn from other peoples' mistakes first. Probably overlaps quite heavily with those people who desperately want to tread on new paths.
The problem is, how do we know that those shouting warnings are not false prophets?
Presumably by reading and understanding their arguments.
But, how do we know which ones we should be reading and understanding their arguments?
