Linux powers 80% of the smartphone market, Half of the computers on the International Space Station, the top 500 supercomputers and the bulk of the internet’s framework. Linux is a kernel. Not to be confused with the many distributions released with that kernel. In creating and maintaining the kernel, Linus Torvalds has repeatedly stated ‘Most kernel development rules we have are just guidelines. The one hard rule I have is to never break user-space.’ Sadly, corporations like Microsoft and Apple aren’t as concerned with that as they are the most innovative features or the best fps for gaming or 4k native resolution for video editting.
Windows and Mac want their hardware to do the heavy lifting for you. You could reasonably use both OSes and never even open the terminal (or command line interface, whichever you prefer); with Linux distros, you could likely do the same but you’d be selling yourself short on what makes the Linux experience everything it is.
