I thought everything will work like before. It didn’t occur to me that my existing environment (all the software I use) must now attempt to run on a new hardware architecture it had never seen before: the Apple M1 chip.

You can still use Bash with Apple M1 chip. You do not need to use the built-in Zsh. You just need to get Rosetta 2 installed.

Rosetta 2 works automatically henceforth

Subsequent launches of x86–64 programs will execute via translation (Rosetta) automatically.
