Sure, but technology also brings its own set of problems, that often the most technophiles wishfully ignore. While replacing humans with robots for boring ("alienating", as Marx described them) jobs is all around a good thing, there is still the problem to what the now jobless workers will do. Fortunately, there are solutions for this one, but it begins with acknowledging the problem.
Similarly, Internet and broadband information allows not only reasonable people, but also any crackpot, hate-addict(*) and/or hardline ideologist to publish themselves. And then, you have a serious problem with information flood and triage. A new saying is that today, dictatorships tell you "Shut the hell up!" and democracies tell you "Yeah, yeah, whatever..."
So you can see new problems emerging because of that : the most powerful becomes the most vocal, which is not always the one with the better argument. You see people having easy access to criminal stuff/violent ideology without control. Which trials come back with a vengeance, but the flames of the stake are replaced by the metaphorical flames of the Internet and the stigmatization that comes with it. Anyone can access receipts for military-grade explosives (and some will even manage to make them without blowing their faces).
Oh, and remember the Boston bombings? Well, some dedicated Internet groups tried to help and identify the bomber(s). Turns out they went completely wrong - now imagine what would happened to this poor guy if the real ones hadn't been identified? And next time, the poor guy could be you...
And that's only one technical advance. There are also genetics, 3d printing, soon antimatter-powered fusion...
So is it worth it? Well, yes! And it's not as if someone could go back or stop those progresses anyway. Will it solve all problems, bring the End of History and the Great Day where all boundaries between humans will fall, and we will all dance together in a flower field with an eternal background sunset? Nope.
The funny part is, the "It will solve our Problems!" is more than a century old. In the nineteenth century, people were already beginning to say that. Remember those talks about the "Global Village" Internet would bring? Well, the exact same talks and name were made when (legal) free radio emerged, and even before with home television.
Also, it is not by chance that the above paragraph uses Marxist rhetoric. That was actually one of the core elements of (Soviet-style) Communist ideology - technology was one of the main elements that would evolve and drive us to Utopia, along with social evolution.
But you will note that no matter how wrong our forebears and parents could have been, and how vast and destructive the consequences were, you will always find plenty of people to make them again as soon as a new flavour is available.
So try not being that guy, and enjoy living in those most interesting times.
(*)Yes, hate is a drug.
Think about it : it is highly addictive, gives powerful pleasure sensations and directly affect higher cognitive functions. Both individuals and organisations are known to use it to herd people, and hate-dealing is a big, very lucrative market.
Symptoms can also include increased physical abilities, acts of violence, wishing for the death of other human beings and increased heart rate.
If you think you are a hate addict, well, sorry no treatment is known at this time, so you are on your own. Good luck.
If you think you are not a hate addict, it means nothing, as most hate-addicts doesn't realize they are hating, often claiming that the hate is from said hate's object. So if you think that someone, -anyone- hates you, or someone you heard about, you are probably a hate addict.
