Generally I try to be eloquent and use the language as gracefully as possible, but directly imaging objects 400 ly away I have only one remark:

A winged drone is a non-starter in a cave type environment
I may have been a bit hasty with that blanket assertion. I should have said "fixed wing".
Bats manage very well in caves - so some form of onithopter might (given suitable materials) do the non-aquatic bit of cave exploration quite well.
A winged drone is a non-starter in a cave type environment, would never be able to maintain enough speed for lift.
It would have to be a somewhat ruggedised standard 4 rotor type thing, to go in water it "just" needs to be waterproof and have the rotors turn a lot slower and ideally have slightly positive buoyancy in fresh water.
Apart from all that it would need to be autonomous as remote C&C under water is non-trivial so all things considered I can't see anybody managing this any time soon.
A robot with wheels or any number of legs wouldn't get to 100 metres in the vast majority of real caves, or if it did it would be unable to return - maybe not a problem?
Can't say for caves in the Americas but the ones in Wales are far from level and unlike the ones on TV don't have suspiciously even floors. vertical pitches are very common and water in stream-ways or partially or fully flooded caverns is almost inevitable.
Must say a submersible drone that can fly above and below the water surface would be an impressive feat if anybody does it.
This is what happens when somebody gets a few facts and tries to extend them using the wrong kind of physics.
Yes, space/time is curved but not as curved as you seem to think.
Yes, if you go in a straight line you'll end up where you started - but - due to the degree of curvature you'd have to go a very long way, many multiplies of the diameter of the observable universe.
If what you said was true we would be unable to resolve any stars, they would all be smudged blurs and not the point sources we do see.
...loading a lorry to take things to a train station, the first lorry journey, unloading the lorry, loading the train, the train journey, unloading the train...
I know, if only there was some form of standard boxy thing that would fit in ships, trains & lorries.
Companies and individuals have used a variety of schemes to reduce their tax burden for decades and while they were just cutting it by a small amount it was generally easier to ignore it.
Now these big tech companies have started to take the piss and reduce their tax burden by a significant amount with the inevitable result that the counties they operate in are getting seriously pissed off.
If they hadn't been greedy idiots, they could have continued with tax reduction for ever, now they've screwed the pitch for everybody (And not before time in my opinion).
Those bankruptcies weren't because of mismanagement as such but rather a barely legal way to reduce debt and screw over all the contractors and banks.
Due to some ludicrous laws in America concerning bankruptcy and Real Estate he was able to declare himself bankrupt and then start up a new business the next day and take over the bankrupt business for cents on the dollar.
In any other country and in America any field except Real Estate, such behaviour would have you prosecuted and disbarred from directorship for a very long time.
With safe deposit boxes you have the only key, the bank cannot open your box without the assistance of a locksmith. That does not stop a third party bank-robber from breaking in but that's what insurance is for.
With cloud services you do not have ownership of the key. Yes you can (and should) encrypt content but metadata is always available and as any spook will tell you, metadata is where the most useful information is found.
Which is why I said "partially".
Obviously they were already investing R&D but the sanctions provoked them to massively step up the funding which will have benefits for them in the short, medium and long term.
Meanwhile in the USA the trend seems to be to cut R&D and boost the already excessive boardroom remuneration.
maybe the policy towards Chinese domination of electronics manufacturing
Brilliant response by Trump, restrict Chinese access to high technology.
So the Chinese have 2 options:
1) Scrap manufacturing and return to a peaceful agrarian existence.
2) Invest heavily in R&D.
Obviously they did the latter and are now overtaking America in many fields and will continue to do so and that is partially due to the idiotic sanctions placed by Trump.
Possibly given how comparatively tiny these switches would be they could be ganged and use a vote system to ensure accuracy.
That is: each element would contain not one but 3 or 5 (or any low odd number) switches and all are given the same conditions and any switches that give a dissenting answer are ignored.
Jupiter is incredibly radioactive which as far as "life as we know it" is pretty much of a deal breaker.
And the problem with "it's life Jim but not as we know it" is we have absolutely no idea how to identify or even recognize it or have a clue as to what metabolites we should be looking for.
About 10p per infraction seems to be the ICO rule.
Woefully inadequate, 10p per transaction is not a penalty, it's an ongoing business cost and far cheaper than sending out mailings.
The fine for this sort of thing should be at least the current rate for a 1st class stamp per infraction.
If corporations want to be "people" then then they should have all the responsibilities the real people have, including paying income tax on every penny/cent of income with the same threat of prison time for breaking the rules that real humans are exposed to.
Obviously throwing a corporation into prison would be "problematical" so the board of directors should be the ones punished for malfeasance.
In fact the entire system of punishing companies for breaking laws is a total joke, any fines come not from the malefactors but ultimately from the customers and workers, for the guilty parties on the board there are no repercussions even for the most serious crimes such as corporate manslaughter.
Uber has consistently lost billions every year because they're more interested in gaining market share than actually operating a profitable business.
Their plan was to first usurp taxi companies to get local monopolies, and then replace all the drivers with self driving cars. They foolishly believed the hype that self-driving cars would be here by now and consequentially Uber is basically fucked, they've burnt up far too much money to ever be in a position to repay the debt.
The next few years are going to have some prolonged death rattles from Uber when the venture capital people finally realize they've been duped.
Doesn't really matter, every frequency is used in multiple locations around the globe, that's not a problem on the ground as you will only get the one that's nearest to you but out in space they are all about the same distance away so extracting a single signal from the mush of multiple signals would be pretty close to impossible.
In fact the combined mush might be indistinguishable from random noise.
Uplink spill might be detectable from a distance but that will sweeping round like a lighthouse beam as the Earth rotates so that's not too much of a concern.
The ISS doesn't have long left, it's likely to be decommissioned within 10 years, probably less so no real point in China getting involved with it now.
The possible replacement, Lunar Gateway is running into political problems so investing in that could be problematical for the middle kingdom.
When the ISS is decommissioned it's possible that for a few years, China will be the only country with a permanent presence in orbit.
Actually they did, UKGov backed every horse in the race which will obviously get you the winner but you also have to pay all the losers too.
Not a sustainable practice but 100% true to established Tory methodology - it gets a few favorable headlines from the poodles at the Daily Mail where the staggering waste of money is dutifully ignored.
Also helps their primary objective which is to make sure when they leave Westminster they'll have nice sinecures to waltz into.
The UK spent £11.7 billion on 570 million doses most of which will never be delivered with no penalty to the non-suppliers
The EU spent £2.7billion for 300 million doses all of which are contracted to be delivered.
And you think we got a good deal? The final cost per dose to the UK taxpayers will be over 10 times the cost to EU taxpayers per dose.
Ah the benefit of misreporting.
The UK threw money at the pharmaceutical companies, the cost to the UK will end up at least 10 times as much per dose as in the EU.
The problem was AZ could not meet the contracts it had signed so it had to break one contract, it chose to break it's contract with the EU.
Strangely in the EU itself there is no narrative that the EU screwed up, they didn't, what they did was wait a bit until the vaccines were ready and certified which meant a one to two week delay over the risky and expensive route taken by the UK.
The only place where the story is the EU screwed up is here.
The business model was to not only wipe out local cab companies but then to replace the contractors with self-driving cars but they believed the wildly overoptimistic timescales from people working on self-driving cars.
Basically Uber is screwed, there's no way self-driving cars will become available in the time-scale Uber was relying on, by the time they are Uber will have trashed so much money it'll take decades to pay back the initial investments.
It's not a Republican or Democratic problem, it's an American problem.
There are structural problems too deep seated to be easily addressed. Perhaps the most dangerous is having a politically appointed judiciary. For Democracy to stand any chance the judiciary has to be independent of the executive branch and be seen to be independent.
Adjusted for inflation, a humble Speccy cost £800. No screen, no mass storage included. And yet people (most, perhaps) baulk at paying this much for a laptop nowadays.
Not really a valid comparison, silicon components are a lot cheaper and orders of magnitude more complex now. Modern laptops probably have fewer chips than a Spectrum but billions if not trillions more transistors in chips that (apart from the CPU) cost pennies to make while those in the Spectrum cost pounds to manufacture. Back then they sold fewer CPUs a year than are sold every day now, economy of scale really adds up.
If you are going to compare then and now prices, you need a product that is fundamentally unchanged. Bread, beer and housing are better products for this purpose. Alternatively citing prices as a percentage of the average wage is possibly a more revealing tool.
European Union members will pay $2.16 (€1.78) for AstraZeneca's shots.
The UK has spent £11.7billion on vaccines.
If all 66 million people in the UK get treated that works out to about £177 per person or £88.50 per dose.
What happened is Boris backed every horse in the race. Try that at the Derby and yes you'll back the winner but you'll lose money big time.
"an unexpected error has occurred"
Actually logical if used correctly.
It just means execution has fallen through the error handling for all possible errors the benighted programmer was able to think of at the time or the testers were able to generate to annoy said programmer.
Admittedly it's not too helpful but followed by a clean(ish) shut down is preferable to a crash.
