Just sounds like you are getting old and seeing that is is fatiguing to learn the same thing over and over again... I mean it is, but that is computing in general. I grew up with DOS and norton commander, then we hit windows 3.1 to learn things, then windows 95x and upwards. Even between windows versions everything shuffled around and I had to relearn where it all was.
Back in college I finally got some unix/linux command line experience, had to learn some stuff there but nothing too deep. In the working world I was back to windows for a while, but a new job got me stuck on OSX and once again had to relearn everything, then back to ubuntu again (What asshole greenlit those scroll bars and 1px target to resize a window?!) and learning more and more.
Oh yeah, there is also the ipad, ipod, iphone, and android devices with their own OS's and quirks to learn too. Not to mention console dashboards and navigating around their social networking features.
I mean, it all keeps changing, and some new stuff sucks, but overall, I think its getting better. I find myself just as lost as I've always been, but the answer is usually auto completed for me when I start typing it into google, I don't even have to search through 30 pages of altavista to find a good webring to browse for good information.
I mean taking the editor, yeah some suck, but some are great, sublime text for example, it is pretty hipster like, but damn, it was really built for people like me. I like keyboard shortcuts but I like GUI's a lot as well and sublime seems to marry the two really well.
So yeah, software changes, more and more TYPES of people are building software for more types of people, there is a lot of crap out there, but filtered out, the gems are really great gems.
