FWIW: Metaverse VR is a flying car category... it comes up every 10-15 years but never gets traction because there's no point to it. Zuck is sailing the ship off the end of the proverbial world when he should've tripled-down on making AR ubiquitous and simple.

#112The west coast of the USA will be a desert very soon. Probably within a few years. Soon 40 million people will be without sanitation water. Then the next step is no drinking water.

#113Tooling for developing real-time collaborative remote working environments is about to take of dramatically. CRDTs [0], while complex to work with untill recently, are now so much easer for developers to use with toolkits such as Yjs[1] and AutoMerge[2]. SAAS and PAAS companies proving tooling around these, enabling developers to easily build collaborative tools for specific niches and verticals are going to explode…
Also, if you want to collaborate, synergize, innovate, and revolutionize consider OTs. They're a known quantity. Handling merges of data is fraught with landmines.
You can't sell 2 of something to the same person offline and know if they wanted 1 or 2. Plus, giving an end user the ability to resolve merge conflicts is asking for theft and fraud.

The idea being that consumer items will, more and more, be able to take DC directly instead of expecting AC. For example, any device that takes in USB power with a 120VAC "wall wart" plug can just be used with a buck convert plug instead or being powered directly from the DC current. LED lighting is taking in AC then converting to DC to power the LEDs. Your phone is taking in AC then converting to DC to power it. You…
How inefficient is the conversion process really though?
The first factor would be the hodgepodge of wall dongles one needs to own and maintain (plus the cost of buying a dongle for each device that doesn't have one, or multiple of them per device in case you want to charge your phone/laptop/etc in more than one location at home).
The second factor is the "smoothness" of your DC sources. Most of the common LED lamps have a pretty ugly signal shape, and not at all close to a DC flat line. This is mostly unavoidable as AC->Smooth DC conversion is more expensive than AC-> DC + a ton of 120Hz, 240Hz,... on top of it. So, common LED lights tend to opt for cheaper "electronics". People notice the flickery LED lights to various degrees (some get headaches, some outright see the flickers, some claim to be totally oblivious to the difference). The DC "quality" also affects some fairly sensitive electronic devices, so some AC->DC adaptors are fairly sophisticated. A central high quality AC->DC convertor (combined with DC wiring) has better scalability when you need to care about smoothness (it can be a basic quality of life matter for some people).
The third and fourth factors are power discipation and conversion efficiency. They are the same thing, with two remedies: more $ to remedy the inefficiency (which is really small these days, if you go for switching convertors), and plans for heat to discipate properly (devices end up with pretty hot adaptors).

>apartment buildings with permacultured gardens growing their own food This has been tried (and proved wrong) countless times. The issue is that it needs a huge footprint, and space is something you don't have at large in apartment buildings.
Good point. I would guess that if electric bikes and other mobility options come online, maybe there will be less need for parking lots to be as large as they are now? Even if apartment buildings are too dense, I still think we will see an increase in eco-village type arrangements.

#118Drone 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.

#119Memristors (sorta) Though small room temp ones don't exist yet, they likely will some day. As to why they are a 'big thing': Imagine a large GPU cluster turned down to the size of a laptop and running off a solar cell. They'd revolutionize electronics in other ways too. But the main use we can see now is that they allow for great amounts of computation for very cheap energy budgets. Stuff that takes coal mines today…

#120We are currently in the middle of an information dark age. Among other things, information in walled gardens will just vanish without a trace.
