Yes installing windows is about as difficult as building a pc. Building computers is not hard unless you refuse to use a part picker site or a prebuilt parts list. Even then, the dude at micro center will pick your parts for you.

Building a pc is just pushing parts in and plugging cables in, not rocket science. Video guides are a thing.

There are linux distros with installers that are windows style, and have a display manager that mimics it as well. Would that count as building on top of existing knowledge? I actually never used something like Mint but if people are putting it on their grandparents computers without issue there gotta be something there.

Convert from apple to another music product and then automate that?

Okay but if I told you Linux was as easy as watching a YouTube video showing how to hang dry wall, then you might rightfully say “this isnt so bad”.

They are comparing the level of knowledge required to do them.
