Joking lol but serious that it will never happen. Windows has waaay too much of a monopoly for that to never happen.
Like wtf, am I supposed to tell my mom to use the terminal to download ms word? Oh wait sorry you can use libre office! It's the same but...... Well it looks different. And isn't as functional.
People around here are delusional a lot of times, but to say that windows has too much of a monopoly to lose market, is too much of an exaggeration. Microsoft has been taking unpopular decisions, newer windows versions have been facing more and more resistance, macos has been growing and taking a share of the market, some governments and smaller businesses have been trying linux as a way to cut expenses, linux usability have been improving a lot, android devices have been taking more steps into taking functionalities from desktop systems and improving usability with keyboard and mouse, a lot of computers that do simple processing have been replaced by sbcs, like raspberry pis, etc.
Windows isn't too big to fail, and it's not impossible that we're close to see it starting to fall. Now, on what os would become the bigger player, that's another story.
Fun fact: My elderly mother uses linux, and without my help. Also, she never used the terminal.
Same thing here my grandparents and some other old age people which i know using linux mint.I installed it to their pc 5 years ago and up to date,it's works fine for them before on windows it was nighmare while they were catching ads malware while browsing the net.
some governments […] have been trying linux as a way to cut expenses
I have been hearing such news for close to two decades but not without news where many such organisations switch back to using proprietary software due to a mixture of reasons ranging from usability to politics.
Windows usage is decreasing every year. Slowly but... And it will reach a point where it will have not enough critical mass to be "THE OS" but "another OS".
I agree that it's not the year of the linux desktop, and that people who think it is are very naive, but you don't need to tell anyone to use the terminal for anything for many distros.
Until you encounter some weird glitch that needs to be fixed using the terminal. It happens maybe once every couple of months for me, but it still happens. Even so, I’m considering switching fully after windows 10 goes EOL.
