bash scripts have their use cases, many things are shorter and simpler than in Python. But coders should bother to learn how bash works and use shellcheck. Just guessing from how things work in another language typically leads to buggy code. Keeping a daemon always running is not a task for bash. systemd is typically much better at that (although something like exponential backoff in case of failure seem to be tricky)
I disagree with his disagreement. I'm not able to overthrow my government to make it illegal for my only ISP to stop intercepting my traffic.

I think you would be very interested to read their takes on HN articles and Fossdem :p
Can you expand on your first sentence with some reasons or justifications for stating this?
For most use cases a guy like him writes a shell script, there's already some well written software.
F.e. in his case, he'd used something like Dagu.
Don't write shell scripts. If you want to do some programming, pick a proper programming language.
