Trolling like that it is no wonder you post anonymously.
I've been using KDE since 1.l0 beta in SuSE, in September of 1998. I tried Gnome but didn't like it and I have never had to install Gnome to get a KDE app to run. For a long time Gnome and KDE dev teams worked together to create a compatibility layer so that each could run the other's apps without having to install the entire DE. It's still that way. I don't have Gnome installed on my Kubuntu Neon 16.04 with 5.73 Plasma5, but I can install Synaptic and run it without installing Gnome, but I run Muon instead.
Your second claim is entirely bogus. Unless you are running Gentoo or Arch or LFS you rarely have to compile anything. VERY FEW apps installed from the repositories have to be compiled, but when they do it is done automatically without the aid of the user. Examples: VirtualBox requires dkms, which requires kernel headers and some compiling, but its all done on the fly during the install. All the user has to do is reboot to activate the change. Installing GoogleEarth causes an automatic recompile of the source but it, too, is automatic. So, requiring the user to be a developer and compile source is NOT part of any of top 100 or so distros, save for the rare exceptions I mentioned. Of course, if you insist on going outside the repository and downloading tar file sources of apps not in the repository then you will have to know how to do a) ./configure b) make c) make install. But NO distro developers I know require that for elements of their distro, save Arch, Gentoo and LFS, and those are not distros that everyday mom and pop users would run.
You stated "When there is a day, that someone can be handed a USB stick with a flavor of Linux that they can run from it,have all their hardware supported, without having to install, compile, or download anything, we will have finally a Linux OS that is at least comparable to Windows 95." How about comparable or even better than Win8 or Win10, and more open and free as well? I have such a USB stick in my pocket as I type. It is a persistent Kubuntu 16.04 LiveUSB. It is easy to make with the mksub app, which is also in Kubuntu's repository. The fact is, the top 100 or so distros in DistroWatch's page hit list are just the kind of distro you claim doesn't exist. There are always the corner or edge cases of hardware for which is difficult or impossible to find Linux drivers for, but if you've spent any time on Windows help forums you see the exact same problem, and that is with vendor configured copies of Windows.
So, better luck next time trying to conflate an experience you might have had with a Linux distro 15 years ago into what you think are problems today.
