The 'labour' in this case is:
Buy ready-made camera stabilisation arm intended for quadrotors
Attach to hand-hold
That's it. That's all he did. Literally bolting one ready-made object to another ready-made object. I was expecting something like using the high-speed servos for moving the swash-plate to and writing his own controller, but this is a VERY low-effort and low-labour approach.

you need to use your brain waves in order to control the ball and make it move

I'm sorry to tell you, but in simple two-electrode EEG setups the chances that you're actually picking up potential differences due to brain activity are near zero. What you have is a forehead-muscle-contraction-controlled game, not a mind-controlled one. An Electromyogram not an Electroencephalogram.

if you could get your hands on a few squids

I'd put constructing a SQUID on a similar level to constructing the main coil. The coil is just a big solenoid wound from superconductors and immersed in liquid Helium (or probably Nitrogen if you're building it at home). Building a SQUID at home requires you to not only construct your own chip fab, but do so on non-standard substrates (you need to make a superconductor-insulator-superconductor junction).

the options are rapidly getting unwieldy for curious bystanders to make sense of.

That's because it IS unwieldy, for anyone. Even EEG done properly is not cheap or simple, and EEG is not a wonderful method of visualising what is actually going on in the brain: you're measuring the potential difference between points of the surface of the skull, and making a guess as to roughly the region in the brain the current(s) that produced that potential difference are actually occurring in based on electrode placement.
fMRI and similar are better, but NOT something you can do at home (just building the superconducting main coil would be a massive feat).

It's a real shame that the two most common representations of cyborgs in popular culture (The Borg and Cybermen) are really shitty cyborgs, with all the downsides of biological and electromechanical components combined (stuck in a humanoid form, lurching about slowly, with rigid 'logical' thinking. They're basically zombies in tinfoil) without any of the upsides. The third most popular is the 6 Million Dollar Man who is somewhat better, but is still stuck in the idea of prosthetic bodies trying to ape the human body. When was the last time you saw, outside of manga/anime or more obscure science fiction novels, somebody putting their brain in a jar, and putting that jar in a non-humanoid body?

What problem does this solve?

Ignoring the Bloody Stupid idea of putting passengers in them remotely, containerising air freight is a pretty good idea. As long as you load the containers evenly, you can just stick the thing under whatever aircraft is available, rather than having to manually load and unload the aircraft itself. Being able to swap (you wings & cockpit only equivalent of) a passenger 747-400D with a cargo 747-400F by swapping out a module would make things very interesting in the air shipping business.

Let me know when somebody actually runs a commercial thorium or breeder reactor.

No Throium (or LFTR) reactors yet, but Fast Breeders? Off the top of my head, PFR supplied the National Grid for almost 20 years, BN-600 has been operating for nearly 35 years, and BN-350 operated for over 20 years.

Even the risk of excessive monocropping leading to a potatoe famine like disaster is not absurd.

That has nothing to do with genetic modification. Remember the Gros Michel?
We've been genetically modifying organisms for millennia, in various haphazard methods: from selective breeding, to cross-breeding, to (accidentally or deliberately) infecting crops with certain organisms, etc. The difference with GM is that we have a good idea of the outcome before starting, and we can minimise unwanted side-effects. The downside is that companies attempt to pattern genetic codes, but that's tied up in bigger IP law issues rather than an issue with GM itself.

If your phone gets stolen you call your operator and read them the PIN. They send out a "kill" signal and the phone commits suicide.

You mean, some sort of international method of identifying mobile equipment? That is reported to the mobile operators whenever the phone makes an attempt to connect, allowing permanent blacklisting of the handset?
Because we have that: it's called an IMEI number. You report your phone as stolen, that IMEA gets put in a blacklist database, and mobile operators will no longer accept connections from that device.
