I think you'd be surprised how few extra features Word in Office 365 has compared to WordStar 2000 considering the forty year gap. And also how poorly designed, inelegant, and - yes - pointlessly bloated Word feels in comparison.

The biggest differences are screen size - full document vs a few lines of text - and support for colours and outlining. Also, PDFs, which weren't a thing in the early 80s.

But the core features in WS2000 are a lot more than a "rounding error" compared to Word.
