The few GNU/Linux users do it for idealistic reasons, or because they're developers, or because they like the latest OS on very old cheap hardware and don't mind to deal with whatever this entails.
The more interesting question is really if freedom exists when you never make use of it. (Do you actually hack the kernel or fix somebody's proprietary binary-only drivers as a GNU/Linux user?)
French interstates work quite well in that respect. Everyone does about 130kph (that's 81mph), and this speed limit is strictly enforced. Relaxed driving, really.
The other thing to take into account is driver training. The kind of tail-gating I'm seeing here in the states rarely happens in Germany. Yes, you get the angry BMW driver flashing his lights at you when you're in "his" lane (road rage is universal), but that's typically over in a few seconds. Drivers wisely keep their distance.
As for this paper, you seem to neglect that even the supposedly continuous, analog computer will have sub-processes that run in parallel, but are correlated and make a distinguishable contribution to the task the global system is concerned with. If you like to picture a network of neurons, then its structure with will one of many separate clusters (a "small world" network, for instance) rather than a random graph.
The question is, does this bring us closer to a computational understanding of how the overall processes work? Localization of function alone doesn't, IMHO. DTI (neuroscience) and cognitive modeling based on architectures (cognitive science) may make better progress.
A PhD really prepares you for a career in research/science, academia. You sound like you're looking to be a programmer (again). Did the reasons go away for which you chose to do a PhD?
Try the big players: Google, Apple, Intel, Microsoft, and so on. They hire PhDs quite happily, and you can apply what you've learned.
It looks to me like their technology is very different (and quite cool: nanobeads? magnetic? proteins?). One issue with the CytoSorbents product is that efficacy has only been proven in terms of reducing cytokines and preventing "cytokine storm", but not in terms of lowering actual mortality.
This new filter seems to remove the primary pathogens (according to the Nature article), as opposed to cytokines (as the submission here suggests).
If they actually ship Friday next week, I'd be surprised/delighted.
They flew in their prototype at last year's AirVenture. The video looks good. What you're going to get is a roadster/plane with foldable wings. I'm saying roadster, because it's going to have two seats - not because it's going to drive like a sports car. This will make it qualify as a Light Sports Aircraft, which means that pilots won't need a medical (important for many). Licensing is a little simpler, too, although everyone I know goes for their full PPL.
As an airplane, it's not particularly fast (93kts cruise - slower than your typical Cessna 172 Skyhawk), and it maxes out at 460lbs payload (full fuel, I guess), if the specs I have are correct. It drinks 100LL or premium motor gas (which is cheaper), and goes some 400+nm, though I'm not sure if that is with reserves (you need 30min day VFR, 45 at night, and typically you want more).
The person working on this at Terrafugia advertised it as a plane that's great for a business trip, because it will get you home most of the time: if the weather is bad, you just land and drive around the weather. That's a neat concept.
The price? At Oshkosh, they were saying around $270k. I asked about insurance, and it sounds like there will be separate insurance policies for road/air use, and it seems that the road policy more expensive than a car insurance (they said 3% of hull value), because of the added utility (more miles driven/flown). I'm not sure if I follow that reasoning.
For comparison, you can buy a used Bonanza for much much less, and you'll get a lot more airplane for your money. You will also get a new Cirrus SR20 around that price point (but that's a plane, and as such not as practical). In the long run, as prices come down, I get see how this is going to be practical for a lot of people that need to travel for work (or can afford to go places for fun).
