I was literally just thinking about this a few days ago. I'm super excited by https://www.nushell.sh/ . I think they are hitting on an order of magnitude improvement paradigm of shells that fit very nicely with the theme of this article.
This goes against the philosophy explicitly mentioned in OP's article. E.g. avoid tabular formats.
This is systemd against init again. A powerful, but overreaching shell that becomes unreplaceable and bloated with concerns. In constrast, traditional *nix/GNU programs work well, and interact well, in every shell.
I think that the shell paradigm could be so much better. If there's a momentum to make a change from that, I'll jump on the bandwagon. Any change is better than the current state of the shell.
