It will never be there. Adobe and Microsoft won’t allow it. There can’t be a replacement for industry standard tools (like Word, Excel, Illustrator, Premiere) unless the replacement becomes the new standard.
I thought about this in the past and disagree. You can already see it with google docs. Office file format interop is becoming irrelevant because the new format is just an url you point your browser to. I worked at a company that used gdocs and had a total of 0 complaints about sending customers a link to a gdoc instead of a docx attachment. There is no need for an industry standard anymore.
As for adobe tools, ok they might still be an issue currently.
Edit: The multimedia things I find really painfully missing in Linux are Izotope RX9 and Kontakt.
