I don't understand what you are trying to say with your answer, as the person said "we used to be working on important problems" and you responded with a list of random technologies. Technologies can sometimes be "problems", and sadly often are :/, but that means that they were failed solutions.
A list of hard problems we could be tackling: 1) the world is going to run out of fossil fuels, 2) we are destroying the human ecosystem by global warming, 3) there exists a very large amount of inequality between the upper and lower class in our society and the gap is only increasing, 4) we have more and more humans of whom society demands "work" to get "pay" in order to survive even as we come up with ways of replacing more and more "jobs" with "automation", 5) there are many subsets of our population divided by axes such as race and sexuality which are discriminated against by others in both direct and indirect systematic ways, 6) we have a limited number of antibiotics that are generally safe for widespread usage and pathogens are adapting, 7) for numerous and potentially diverse reasons an increasingly large fraction of our society is being turned off of science and has stopped believing in basic things like the benefits of even our oldest and most trusted vaccinations, 8) humans continue to die from diseases like cancer, 9) governments and companies have begun to usher in a dystopian era of surveillance under the guise of protecting us from terrorists and spam and serving us advertisements.
A couple of these problems can be addressed with the technologies you listed, but even in the core of some of these communities that want to address problems 5, 7, and 9 you honestly just end up finding a lot of people who are exacerbating problems 2, 3, 4, and (annoyingly) 9.
I despise the cloud :(. It was just so much harder for people to abuse the crap out of us when the concept of a computer was something that, even if it could connect to other computers to get information, was not something that fundamentally relied on other computers and which stored all of its information on other computers and could be remotely controlled by other computers. We are to the point where arguing that I "own" the device on which I am typing this message almost doesn't make sense: I am borrowing it from Apple and I can only hope that they don't screw me too hard :(.
