Another said that Windows 10's spyware aspects made him give up on his beloved PC platform and that he will use Linux and Android devices only from now on
Sounds like someone is in for a rude awakening about Android. (I think Win10 is worse than stock Android re:data collection, but if your primary concern is privacy...)
As to the question itself: It absolutely is, for varying definitions of "cool" and "fun". I'm a 90s kid (so many things I have to remember) so I didn't cut my teeth on a C64, but as a youngling I got sucked in by the potential of PCs and what I could do with them after discovering epic tools like "dir" at 12. (Oh, and playing Zork.) There's still a tremendous amount of potential, but a lot of us have turned what were once hobbies into jobs and started specializing in a sub-aspect of computing. The former can easily deprive the "cool" of the hobby if your job is a negative aspect of your life (and thus whatever "computing" you do is associated with that negativity), and the latter limits the "fun" because the simple problems are mostly rote at this point and discovery means chasing the long-tail, if at all.
In my case, a major lure for general computing—that made it "cool" or "fun"—was that discovery. While I've lost my own wonder and interest (for varying reasons), there seems to be as much uncharted territory now as there was in the 80s/90s: augmented/virtual reality, Internet-of-Things, alternative inputs (particularly in motion controls and applied to VR), biomedical, brain interface (both direct and indirect, such as simple headgear that react to brain waves). Computers are far cheaper and more powerful than they were, with software that can allow Joe American to start basic 3D modelling with something he picks up at Best Buy.
Computing itself isn't necessarily static: I think we're going to see computers in general converge, where either your phone/tablet is also your main PC, which, when docked, has more processing power (Nintendo's upcoming Switch is reported to work this way, in fact) or "always-on"+"cloud" means your various devices are just UI for data on the internet. Regardless of which direction you prefer, either will be enough of a shift to provide tons of creation/discovery potential driven by demand.
A point of general agreement was that big tech companies in particular don't treat computer users with enough respect anymore.
A bunch of assholes deciding against consumer interests (and then consumers rewarding them for such) doesn't deprive computing of being "cool" or "fun"; it just means you may have to seek alternative platforms depending on the aspects of computing that drive you and how you want to enjoy that.
