If gamers move to linux I don't see my current CTO holding a staff meeting saying we are throwing all the windows desktops ,servers, application licenses out to go all linux because that's what the kids are using.
You are thinking too short term. Kids grow up and use what they grew up with. I didn't say it would happen over night.
Not every kid grows up to use "what they used when they were kids".
If that were the case, I would never have bought a Windows PC in my entire life. Although my parent's first "real" PC (that was used as an actual PC, rather than a glorified word processor/stand-in for the Colecovision console -- our first actual home PC was the Adam, complete with daisy wheel printer & cassette tape drive), the first PC I ever used (& used quite a bit in school) was
Apple: first the Apple II+/IIe in elementary school, then a short veer-off to the Commodore 64 in middle school (that's what the "computer lab" had, think glorified & expanded broom closet), then back to Apple IIes in high school -- although we ended up getting the first Macs as part of that "collect your box tops" program.
Yet today, while I can work on a Mac, I find it much more difficult to work with than a Windows PC. Probably because, when I became an adult & went to college, those Macs started disappearing (at the first college I attended, of the 20+ some computer labs on campus, only 1 or 2 actually had Macs, & even then they were split 50/50; at my second college, there were no Macs to be found, just PCs rocking Windows 3.1, then later Windows 95). Even at the college my wife teaches at, there are very, very few Apple PCs there -- & over 90% of them are issued to instructors for their use in the classroom (both in Macbook & iPad format), not for the use of the student population.
Not to mention that people can be "gamers" who have never touched a PC in their life. Of my 4 nephews, 2 of them are "gamers" who primarily game on game consoles (mostly FPS shooters on XBox 360), & are secondary "gamers" on their iPads...but I don't think they've really used a PC, let alone done any gaming on it (& have no idea why WASD & 2-button mice are so important in FPS shooters). Their dad is the same way; although he uses a PC quite a bit (especially when he was in charge of the maintenance guys in his unit while in the service), & plays on the XBox quite a bit with them, he hasn't played a PC game for some time (last time might have been the late 1990s, one of the old Windows 3.1 Formula 1 racing games). The other 2, however, are like me & their father: avid PC gamers (my brother-in-law & I would spend a lot of time when we got together for family things hooking our PCs together to play Starcraft or Age of Empires I & II; nowadays, we still play Rise of Nations, Age of Empires III, & -- before Windows 7 ganked it up -- MechWarrior 4; used to play SWAT 3 & 4, but he thought the language & blood was a bit much for the kids), with a little bit of gaming on our Wiis. So, you can have "gamers" that might not even know what the term "operating system" is (nor why there are such crucial differences between Windows, Mac OS X, & the various flavors of Linux), or you could have "gamers" that actually know their way around a PC.
And that brings up the final point: we usually don't control the hardware/software decisions. Maybe you're lucky enough to work at a company where the "IT Deparment" is actually the entire company. Maybe you work at a company where they really do grant the various divisions full autonomy in deciding what hardware & software they're going to use (although I'd hate to work in that IT department). But for the vast majority of us, the organization we work for either has specific guidelines for what hardware & software can be purchased (as determined by said IT department), or the IT department has been told that, as long as they can keep everything running semi-smoothly, their main consideration is going to be the cost (both up-front & ongoing for support). Which is why the vast majority of offices don't run on Macs: for the cost of purchasing 2-3 Macs, you can usually buy 3-5 Wintel/LInux-capable platforms with comparable hardware (the core i5/i7 chips running those Macs, after all, are the same models available to both other OEMs & DIY types). And until Linux can get to the point that 90% of the Windows/Mac OS X software is available for Linux -- or at least really, really good alternatives (
not "well, App B for Linux
kind of works like App A for Windows, but it doesn't have features G, H, X, & Y, & you have to use a 3rd program to convert the save files over to the new format..."). And yes, that's important, because the more changes you make to your apps, the more time the company has to spend on retraining the employees to use the new apps. Heck, I remember when we switched over from Office 2003 to Office 2010 at work, & they made available to us some DIY training aids & online training courses to spotlight the changes made between the versions. While my co-workers use a PC in their daily work, I would say that for various reasons the majority of them are
not what you can call "computer savvy", or even "comfortable" with computers. Which is why I don't use Apple computers for work like I did in school as a kid: the companies & organizations I worked for & currently work for do not use Apple products, so I have no choice in the matter.
Let's face it: we gamers, computer geeks/nerds, & DIY PC builders are still in the vast minority. And even among us, only a literal handful can end up being a Steve Jobs, Bill Gates, or Elon Musk, starting their company from scratch & therefore having the power to decide what flavor of PC we want to utilize. The rest of us are subject to the decrees & whims of our bosses, & most of them don't see any correlation between gaming trends (PC or console) & the needs of their operations.
