They just don't know it, and the people hiring them don't either.
It's not a new phenomenon, we got the same when Java arrived, then PHP, etc.
Every time something makes things easier, you get a wave of beginners set to create things they are not qualified to do. And because you now need software for everything, leaders also get into positions where are not qualify to make some decisions about it. You pair unqualified leaders with unqualified devs, and you get this.
And it's now easier than ever to be in this position, also you are more pressured than ever to get into this position.
I've worked on plenty of big Python systems myself, it's not the tech per se (it has the usual pros and cons game like every language), but Python is the language used "when you don't know programming".
Which is ironic, because when I started to use it in Python 2.4, only passionate devs used it because it was niche, and we had the opposite effect.
