If Time Had Frozen 30 Years Ago by Autumn Snow

Let's face the facts here. Life in 2018 isn't all that it's cracked up to be. Now, life in general is another story (in some situations), but honestly, the past ten or so years have been pretty darn . . . well . . . boring.
Depression and anxiety rates are higher than ever before, as well as teen suicide (which is almost always linked to depression). Of course, these things have been going on since the beginning of time, but if you look back 20+ years ago, such occurrences were fewer and farther in between.
Take the 80's. Man, do I wish I had lived to see the 80's. I feel like they should have taken the "Roaring" out of the 20's and put it in the 80's instead. Of course, I have no personal experiences from this time era, but it's far more interesting to me than the modern day. This decade was filled with iconic movies (Steel Magnolias, baby), amazing music (Bruce Springsteen, Elton John, Barbara Mandrell, Bonnie Raitt, etc.), and just about everything that has ever been appealing to me. But this is us, we're talking about. This is the statistics of the world, so let's get back to it. Though technology has advanced a significant amount over the past few decades, it's hard to say whether it's for the better or not. I mean, we already had the television, the radio (aka the pinnacle of happiness), the telephone (sorry, kids, no iPhones in the 80's), and so on. Did we really need all of the same things in "better" forms? I think not. Twenty/thirty years ago, people used the telephone to call people and talk to them. Texting had not been invented until 1984, and the first text message had not officially been sent until 1992. Even then, texting on cellular phones wasn't utilized regularly until the early 2000s. There was no YouTube, no PlayStation, no Facebook, Snapchat, Instagram, etc. So what in the world did kids from about a generation ago do? Whatever did they come up with to entertain their young, impressionable minds? Well, there was always music. "Summer of '69" would probably have been blaring through the speakers of your cassette player while you did your homework. During the day, you might have tried to catch Full House or Growing Pains on the box television in your living room. The thought of doing something "more interesting" like watching cat videos on YouTube or scrolling through the newsfeed on your social media account would never have crossed your mind because such things had not yet come into existence. And you would have been absolutely fine.
My personal opinion on the modern day is pretty negative, but again, it's just my opinion. I (personally) think that, 30 years ago, the world had most everything it needed to be the convenient world it had already become. Now, things have gone so far that technology and such have become quite inconvenient in most aspects. The cellphone has become man's best (and only) friend, the internet can be a dangerous, dangerous place if one isn't careful, television certainly isn't what it used to be, and I could go on. So, the gist of this post is more a question made from an observation rather than the answer to the problem. And we all know we've asked this question ourselves once or twice when dwelling in the deepest and most profound areas of our thoughts. And that question is . . .
Dude, if we're so technologically advanced and stuff in this modern time, then why hasn't somebody gotten around to inventing a time machine yet?
