Honest question…given how developed our sensibilities are around docs, file storage, and spreadsheets, what is the hard part to this?

Don’t get me wrong…something is hard…I still use Microsoft Word because I feel like I have to. But what is keeping the industry from building a word processor that doesn’t suck and is capable of interfacing with .docx files?

Word has a billion features you did not know that exist. Getting something Word shaped is probably straight-forward enough (how long did it take to make Google Docs), but getting those dangling features and quirks would be a long haul.

Mimicking Excel - woof. This one is used by so many people in different ways, that unless you offer 1:1 bug compatibility, it would be challenging to get 100% of people to meet everyone's current use case.
