I've been using bash since the early 90s and I'm now in my 40s so I think at this point I just have to accept that I will never use another shell.
On Macs, the current version of bash can be installed from Homebrew and you can set it as your default shell in the SysPrefs, in Users > Right-click you > Advanced
