vi and vim have modes because they were created in an era where computing and terminal capabilities were very limited and even when the terminals could support interactive editing, it wasn't expected. They had very low expectations. They were used to things like 'ed'.
The religious beliefs that programmers have about vim are a case study in why I believe that AI will easily take control of the planet in less than a century.
That sentence is questionable in multiple ways.
Anyway, I will definitely try this thing out. Hopefully I am not too lazy to keep installing it. That's what happened with the last one of these.
