I'm not sure enough people are talking about Demographics and population decline, especially with respect to China. Some experts [1] predict that China's population in 2050 will be HALF of what it is today! [1] https://www.barrons.com/articles/china-xi-jinping-economics-...

Way to many people work on filler jobs that will go away and automation will also solve a lot of the problems. China has about 22% people working in agriculture, that will go down a lot over next two decades.

farmes are almost untochable, like in india but without voting power. nobody want 22% of its uneducated population making trouble in the cities. Hukou aka stict residential permits almost serve that purpouse

Also, others made the point already about rent for the space to park on (most likely outcome would be high taxes and rent for RV parks I can't speak for everyone but the way I would circumvent that would be to buy a piece of unrestricted or minimally restricted land that allows an RV as a primary dwelling. This requires some research on youtube among the existing RV nomads. Non-farmable land is very affordable. Some…

I literally did this. My recommendation is just learn how to repair the RV yourself. RVIA has an online cert program you can take for $300. I know how to repair RVs and I just had to pay $6700 to repair a $55K RV before selling it. Do not underestimate how expensive RVs are to pay someone to fix.

That's awesome that you did your own training. Agreed the RV's, especially the less common platforms are crazy expensive to have someone repair and that is assuming one can even find a mechanic that will touch it. That's why I suggest using a common platform if one can manage having a smaller RV. One example would be RV's based on the Ford F450/550 platform [1]. There are plenty of Ford mechanics and I envision Ford some day having an EV or hybrid version of the example I linked. Linking overpriced example, there are more affordable examples

The people that build "custom schoolies" are especially on their own unless they are part of many forums/facebook groups of schoolies and can find a mechanic that knows how to work on school buses.

Drone tech is going to get tiny. It’ll have microphones and cameras and it’ll probably be untraceable. It’ll spy on you arbitrarily and the equivalent of 4chan will have access to it in abundance. You will never again have any form of privacy unless you buy expensive countermeasures for your home and office. Fortunately deepfakes will be so good you can blame it all on that.

I'd rather expect drone tech to be increasingly regulated or banned. We're going to start seeing it used as a weapon more and more. You can see simple forms of it happening the Ukraine conflict now.

I am under the impression that instead of preparing for climate immigration, EU citizens are actually slowly but surely mutually brainwashing themselves into increasing hate towards immigrants as a whole. From what I read and understood about climate change, a tsunami of immigrants from southern hemisphere countries towards northern hemisphere countries is to be expected. I would rather have my elected ones work on a…

Outside observer, but my understanding is that a big concern is that people from more illiberal cultures will make the nation more illiberal. There is also concern that making low skilled labor more plentiful will be harmful to the prospects of existing low skilled labor. A third concern would be that if the immigrants express an ethnic preference for their own community, this will cause increasing difficulty for exi…

Agreed. It seems to me e.g. Germany is very open to immigration in all forms, IF, immigrants are willing integrate sufficiently into the EU value system concerning equality of sexes, blindess towards ethnicity, freedom of religion etc. They're not brainwashed at all, they want to keep their culture free of brainwashing.

How does rebuilding manufacturing work? Does it look the same as it did 50 years ago, or is it different? What happens if the attempt fails?

Robots this time.

Can you elaborate? "Robots" is more a slogan or even a metaphor than a plan.

Tbh, if there was demand for it we'd probably have them already. I'm afraid the most demand would come from those engineers who create the apps that glue everyone to their glowy screens, and from the sort of parents who have a zero-screens policy (those would be for themselves). Hardly a market that will get any VC excited.

Energy? I feel like it's been talked about a lot but maybe not? Solar panels are dropping in cost at an exponential rate [0]. As of this writing, consumer "new" panels are $0.75/W and used are at around $0.30/W right now (I won't give a link as a Google search will do). Battery technology is also dropping at an exponential rate. I believe, with a little effort, one can purchase batteries at about $0.08/Wh. Taken toge…

> which puts the return on investment (ROI) at about 3.5

Fyi, that's time to break even. ROI is measured in % (annualized, usually).

Personal vehicles will be getting both bigger and smaller. What's different from the past is that electric motors scale much better than IC engines. Both the world's smallest vehicles (kid's toys) and the largest vehicles (huge mining trucks) are both electric. First the small. Cities will soon start to ban all but electric vehicles in their downtown cores (already happening in some Chinese cities). The primary reaso…

Please change electric to battery powered... I don't think the largest mining trucks are battery powered. They have diesel generators that power an electric drivetrain.

It depends upon where you are loading up your material. There are huge electric dump trucks that make more electricity carrying material down the mountain than they need to us to drive empty back up the mountain (45 ton eDumper).

Likewise the emergence of analog outputs from a computer would be fun. It may be niche at first, but imagine if the output was moving some wooden sculpture or the output changed an analog letter board. Would create a bit of permanence rather than everything digital being so transient.
