One funny thing about humans is that they aren’t just gloriously fallible: they also get quite upset when that’s pointed out. :)
Unfortunately, that’s also how you end up with blameful company cultures that actively make reliability worse, because then your humans make just the same amounts of mistakes, but they hide them – and you never get a chance to evolve your systems with the safeguards that would have prevented these.
It… depends. There is some great tooling for Python – this was less true only a few years ago, mind you – but the landscape is very much in flux, and usage of the modern stuff is not yet widespread. And a lot of the legacy stuff has a whole host of pitfalls.
Things are broadly progressing in the right direction, and I’d say I’m cautiously optimistic, although if you have to deal with anything related to conda then for the time being: good luck, and sorry.
