The fastest computers on the planet run Linux.

Variations of Unix perhaps, not necessarily Linux however.

It is the most popular OS on the planet

Very doubtful. Of course you would need to define "popular" to have any
meaning at all.
IME Apple OS is the most "popular" (largest number of fanbois) but
definitely not the most widely used. Do you count it as "Linux" though?
(it's not by any normal definition)

(or soon will be).

More unsupported speculation.

If there is a task there is an application for it.

Agreed, unfortunately they are often rather poor for consumer applications,
and drivers for a lot of hardware in current use by consumers is often
lacking also.
For server use Linux is king, for consumer applications, definitely not.
I've been hoping for a decade or two that will change, still waiting
unfortunately.
No one is stopping you using whatever you like though, but your fear of
Windows is not shared by everyone.
