Especially if computers are not your life, but something you want to - say - weekly - write letters on.
Once you drop the frequency you're doing something, learning gets lots harder, even for the young.

'without cognitive impairment'.
'cognitive impairment' is a hell of a lot more gradual than you think.

For someone using computers a lot, they're probably going to figure it out.
For someone not using computers a lot, and who have managed to do things by remembering exactly what to click - this is enormously fragile.
Issues from 'I might break it' -> 'I might put it in a mode I don't understand how to get out of'

Someone in this position may not be able to recover from an expanded list collapsing down to a tiny triangle on a mis-click, especially if this is a feature that they will never need.
Or icons changing from ones they know, or menus moving around.

This article was brought to you by the makers of quality monitors, that are all you need, and do not cause your brain to melt like goggles do.

That would rely on the steel being magnetised, and repeling the board.
If the superconductors are simple magnets, then all that happens is you have a big clang as it clamps onto the surface.

'A steel surface' - bullshit.
A closely packed array of magnets - maybe. (magnetised steel is not enough).
Aluminium - again sort-of-plausible at high speeds.
But - not steel.

This is not referring to a decision of the Supreme Court of any EU body.
This is stating that a decision made under national estonian law is not incompatible with the international treaties that Estonia signed.
It has as much bearing on the rest of Europe as if a state in the US decided to legalise certain drugs. This does not mean they are federally legal or legal in other states.

This is a EU decision saying 'Estonia has the right to make this law'. If Estonia was not a member of the EU, then the original defendant would not have been able to appeal (and fail) to the ECHR, the decision of the Estonian courts on an Estonian matter would have been enough.

And what if the segment you're entering into is _all_ subsidised by the government, and you do it for less subsidy or payment, reducing cost?

Employing mainly Americans, manufacturing in America.

To be fair, I suspect the number in the article is off by several orders of magnitudes (low).
I should really check the original article.

It gets stuck in some species guts, and some smaller invertebrates guts dramatically reducing their ability to feed.
It is an actual problem.
Another major issue is the beads attract pollutants onto their surfaces. These are then efficiently transferred into whatever ingests them.

There is very little reason to be using plastic microbeads, rather than - for example - wood.

471 million potatos is a lot of potatos.
471 million .2mm bits of plastic is enough to cover in plastic all of the living rooms in California.
Wait - no - one living room. Or about a dinner-plates worth a day.

The article is misleading - if you click through to the website, the actual video of the thing shows the prototype shows the tubes as ~1m long.
The volume is about right.

That is not - quite - true.
However, they nowhere I have found have an actual picture of this thing in flight, or a video.
Then there is the fact that if you actually follow the links, they say something problematic.

The vehicles weight is 4kg.
The hover power is 400W.

This is very low for the weight.
Low power isn't purely a good thing.
Lower power implies a much lower 'exhaust speed' for the fans, and consequentially, much worse handling in wind.
If you rip out the (say) 1.5kg of fuel cell and extra structure to do hydrogen storage, and replace it with batteries, you get - with the same hover power and assumptions - over an hours flight.

Quadcopter flying times are a trade between ability to handle crosswinds and power-weight ratio.

If your quad gets blown away in winds a little faster than walking pace, you have a problem.

'the pain will be staggering' - and also not helpful.
You've just vastly incentivised gold-extraction from seawater, mining gold in conflict areas, burglary, and shifted truly insane amounts of money to the indian community who like to hold wealth as gold.

Why would you want one person per one truck, when you can have a customer service team with one person per hundred trucks?
