The primary magnets will be super conducting magnets. Unless you have liquid helium (or liquid nitrogen, if your lucky) to cool it, it will just be an interesting rock.

Of course not, that would be immoral. They'll track trollies and baskets, then tag it to the till and your loyalty card. It would be a lot more consistent, and harder to dodge.
I can see multiple uses for the tech. Unfortunately, many are a but dystopian, but some are legitimately useful.
I don't know if it's real or just nostalgia, but reddit is massively worse than I remember. I've gone back to nose a few times, and it feels like a ghost town, compared to what it used to be.
The executive functions are a tiebreak system, in many ways. It balances the various possible options, both benefits and costs, short term and long.
Procrastination is when this system can't overcome various situational inertias. I tend to think of it akin to a teacher in a classroom. The kids are perfectly capable of raiding a kitchen, when sufficiently hungry. It's also impossible to keep them focused on maths, when a dozen labrador puppies are released into the classroom. Within its limits however, it's supposed to turn disparate drives into coherent action.
I have adhd. The teacher is exhausted from a 3 day bender, and someone swiched their coffee to decaf. Avoiding situations that cause a procrastination lockup are a fact of life.
HDDs can be made tolerant to it. Constant rotation still puts significant extra strain on the bearings, when spinning however. The drive will likely fail faster than an SSD.
Your best bet might be to use a laptop as the basis. They are already designed with power efficiency in mind, and you won't need an external screen and keyboard for local problem solving.
I would also consider having a raspberry pi 3 or similar as a companion. Services that must be up all the time run on the pi (e.g. network admin). The main computer only gets kicked out of sleep mode when required. The pi 3 needs less power than the newer pis, while still having enough computing power to not lag unless pushed hard.
I definitely agree with SSDs. HDDs don't do well when rotated when running. Boats are less than a stable platform.
I've been places where neurodiverse is a significant majority. It's amazing how friendly and straightforward people can be. It's particularly funny when you see neuro typicals suddenly finding they are on the other side of the mirror.
It did well for a long time. The BBC produces a lot of excellent programmes. It was also unafraid of holding the government's feet to the fire.
Unfortunately, the Tories successfully gutted it about a decade back. It still produces excellent programmes, but is neutered politically.
As for the licence fee. It is effectively an extra tax. However, if you don't watch TV, you don't have to have a licence. It's not perfect, but better than just a flat tax. It also helped keep them semi independent of the government.
Thatcher, may she burn in hell, was far better than Farage. She at least had significant political skill, and an actual plan for the UK.
Farage is a grifter of Trump's mindset, but a few more braincells.
Screw thanking aliens, it's an incredible team of engineers that have the skills and dedication to do what seems impossible. This was 100% humanity at its best.
They rebuilt the most critical core code on a near antique spacecraft that has effectively left the solar system over an equally ancient radio link. They had 1 shot, and nailed it.
It takes some practice to beautify it. You'll also spend more time doing that than the whole time taken to build the core.
