Seems more like political problems. They have been trying to build large wind farms and export cables for years. If they can't even manage that, they have no hope of building nuclear.

It's a tragedy really. They have massive amounts of space for this stuff. A lot of sun, and good on and off shore wind resources. The domestic solar market is actually doing okay, because it gets less political interference and there isn't all that much that can be done to stop people putting panels on their homes.

I would be surprised if software updating an aircraft is that simple. It probably needs to be controlled and tested after the update, with records kept by maintenance staff, and notifications sent to pilots.

It's true, they had a shortage of shadow puppets, the early form of Netflix.

I wish more would choose Jainism over Islam and Christianity. Many crave some kind of religion, and if such people picked the more peaceful religions there would be fewer busybodies trying to force their beliefs on others.

can the researchers really say with confidence that the civilization would still be with us today?

Nobody claimed it would otherwise still be around. You are putting words in their mouths. It only solved, or at least partly solves a mystery. Usually declines of ancient cities can be traced to invaders, civil war, damaged soil, plagues, etc. This one had no known comparable cause.

Is it possible the smoke & soot from the city changed the local weather?

They have to wine and dine a few gov't officials before that step.

They found out somebody accidentally installed Boeing bolts.

This will EU's problems, no doubt.

I'm sure you do.

Imagine how different the U.S would be today if every penny of it had going into domestic social spending, high speed trains and the like.

They ran out of stuff to watch on Netflix (etc.)

The weird thing about that scenario is, they made it into a kid's movie.

You're not thinking it through -- the goal isn't just to put everyone on benefits and make them spend the rest of their lives clicking the TV remote and waiting for their next welfare check. If you want to do it right (and the robots provide sufficient surplus resources to support it), you go a step further and hire people to do the job they always wanted to do, whether it makes a profit for anyone or not. If that means we have 100,000 ski instructors and 300,000 mediocre artists, then so be it; the robots do the grunt work, and the people are paid to do their preferred avocation.

Not that I expect that to actually happen, of course; in the event the robots actually can replace all labor, the upper classes will make sure that economic surplus goes to themselves, with only the absolute minimum getting distributed to anyone else.

Honestly, they don't "need" robots or anything else; they could just keep doing what they've always done and hope for the best.

However, unlike some countries I could mention, the Chinese government has a vision of what it wants its future to be like, and is willing to work and invest to realize that vision. Hence robots, and other economic development.
