Maybe a fine desktop for the top 1% of people (developers) where as over 99% of general users in the world regularly use Windows and macOS.

General users mostly need the proprietary software to do their basic work. Some want Microsoft® Office (Especially Excel®, not LibreOffice Calc), others want Adobe® software, another needs Autodesk 3DS Max and they don't want to play with their OS if something is broken which is what you'll always get with a Linux distro.

No person can take desktop Linux seriously if they still ask about this software still being missing in Linux. It's back to macOS and Windows for them.

Have you heard about Office365? Been using Linux in corporate world with Outlook, Word and Excel via web. Never had problems with it.

It's actually kinda surprising how many developer tools I play with that either only run on Windows or clearly have Linux as an afterthought.
