Many senior devs over the last decade have been created by boot camps. With the recent lay offs the over supply is becoming more apparent. It is now really easy to hire senior python devs.
Arguably python is so easy that junior devs aren't that far off from senior devs.
Sorry but this is nonsense. Juniors can absolutely make a huge mess in python if let to their own devices. You seem to confuse the knowledge of syntax and language features with actual experience in designing software.
I guess it depends on your definition of "senior", but I don't see why language choice should affect it this much, given that much of what makes seniors senior is not knowledge of specific tech, but experience with software engineering as a process.
This^ is true. Arguably though the majority of web development doesn't involve the stuff you mention. Developers simply work within a framework. This Linux stuff is relegated to specialists... devops or security engineers.
