One thing which is subpar about such an interface is that you basically have to type "help" unless you just want to blindly guess what the commands are. This is like a landing page that has a button that says "show what sites I can go to from here": why not just show my options straight away? Unnecessary indirection.
Gratuitous negativity violates HN's guidelines and is not welcome here. If you have criticisms to make, make them substantively. This is not a site for spewing bile.
Whereas the novelty of rude remarks for no real reason keeps on giving!
You are suggesting using screen space for the use case of a new user. Some people optimize for people that are already familiar with the program.
Both are valid options, so it's a bit silly to criticize just because it's not your preferred use case.
It's a landing page, man. Unless you're a celebrity, you should "optimize for new users".
