> with more screen time and less real-world socializing That would imply that girls overwhelmingly don't do the same, which is not the case. Maybe it's online dating https://www.icoderzsolutions.com/blog/facebook-online-dating...

Maybe girls do -- do the same. Say 20% of girls do the same, that takes those girls 'off the market', so there's more competition and less supply of potential 'mates'. I mean it sounds like a black mirror episode but, there could come a day where nobody leaves the house and everything is done in a VR world, including relationships and sex. Of course that might be healthier than what's going on now, at least there's s…

ok but the studies show that the phenomenon is more prevalent in men. it's the nature of the sexual marketplace that is skewed towards males -- liberalization and competition on steroids as in online dating leads to pauperization.

but is it more prevalent now than pre-facebook? If not then that would support my hypothesis that online culture is adding to it, and possible causing some of it.

We can't make real progress on a lot of other problems unless that is addressed. There's always calls for more housing in the cities, but it's going to be real hard for the cities to support growing populations if transportation infrastructure becomes harder to maintain, if coastal land is encroached by the sea, if water supplies can't be secured. If large-scale agriculture isn't sustainable, cities won't be sustaina…

Maybe we can reduce our reliance on cities. The main thing we need is ways for average joe to make a living outside of the city. Remote working would help. Maybe those dying shopping malls become shared office spaces, and you pick your office and your company separately. You get the social side with people working for other people in the same room!

Sure that is part of the solution. But when everyone is shouting for more housing in already densely-built cities, it's hard to tell everyone, move to somewhere where there's still more space (though that is happening to some degree, just by basic economic force).

The graph of OP suggests so

People with different viewpoints can't talk to each other. Or rather, on several important topics, too many people can't or won't talk to people with different views.

I'm working (slowly) on that one at http://WarFlagger.net/ as well as the fake news/fact validation issue.

Allergies. Something has changed to make us allergenic to a degree that was never previously the case. We need to understand and fix it.

Is this true? Or did we just not care about allergies before when we had much bigger issues (like dying at age 30)? Some reference/data to back up your claim would be nice.

Graph Theory in the presence of modules and dependencies between modules. Every thing in computing is modular and multiple levels of modules and has coupling and dependencies between modules. It's the hottest and hardest problem in real world computing... it's nicely representable in a graph theoretic framework.... but graph theorists aren't looking at it.

Can you provide more details? Are you talking about algorithms like modular decomposition[1]? Any specific challenge you'd like to see addressed in the following years? [1] https://en.wikipedia.org/wiki/Modular_decomposition

Especially automatic refactorings...

If you look at real code, often the main reason why this routine was added to this file... was that the programmer worked in this file last.

Is that a Good Reason? No it's a bloody awful reason.

An automated tool should be able to look at the network of declarations, definitions and references and work out which module each thing should be in.
