Well, Typst isn't directly comparable to plain TeX given how low level plain TeX is. Typst also poses itself as a LaTeX alternative, rather than that of plain TeX. So, I think, it'd be more prudent to compare between Typst and LaTeX.
For beginners, Typst is much easier to get into compared to LaTeX. Typst is also much faster at compiling documents. Error messages are also clearer in Typst. Typst itself is compiled to a single binary, so local installation is as easy as just downloading it and putting it into a directory that's available in $PATH.
I might as well also mention that the Typst web app runs on webassembly (meaning that the browser does the compiling instead of some server), so there is no compile duration limit like that of Overleaf.
Yes, LaTeX is huge with its many years of development and layers upon layers of abstractions glued on top of one another. This is also why a new start was necessary, this is where Typst comes in, in my opinion.
By complaining about copypastas you are just making it worse. Can't you see that? Every time you comment and complain about people posting the same comments each time just adds to the incentive for people who think they are funny to continue. I am willing to bet that this comment will turn into a *** copypasta at this point just because of how "funny" and "ironic" it would be to make a copypasta out of a comment complaining about copypastas.
