Top 10% owning 10% of wealth makes no sense as it means perfectly equal wealth redistribution. It is an ultimate goal, but it is not practically achievable. 20% is close enough.

I ain't no physicist, but the last time I've checked, it was a theory galore, with theories upon theories about whether there could even exist a single definite theory of everything, with stuff not being observable by it's nature (quantum particles), other stuff not being observable by it's nature (beyond observable universe), and theories based upon the event of literal creation of the universe itself, which is in turn theorized by linearly extrapolating a single phenomenon all the way down to zero (correct me if I'm wrong on this one, shit's fascinating).

Finding how dinosaurs sounded like, on the other hand, doesn't take much theorizing - just take some well preserved remains, approximate breathing cavities structure and model it with something like a pink trombone. I'm oversimplifying, of course, but, the point is, it's miles closer to us, time and space wise, than whatever physicists are rambling about.

Nobody tell this guy about the state of modern physics.

Not necessarily. Even though PS/2 operates with a superior protocol, latency-wise, the clock speed is atrocious, resulting in an effective polling rate of about 1500hz, give or take. We could account that it doesn't need to wait for request to send keystrokes like USB keyboard do, effectively doubling it even more, but then we'd have to account for whatever delay Super I/O chips introduce and I'm not qualified to talk about that. But, if your keyboard is not from a dollar store shelf then it probably runs on at least 1000hz, at which point we are talking about sub-millisecond differences which would be quite hard to notice. 4000hz keyboard definitely beats PS/2 though.

Nothing to do with the interface. If your keyboard can only do 4 it means that the manufacturer has cheaped out on diodes and couldn't even be bothered to stagger the matrix enough to make you not notice.

It's actually the other way around. Check out Ben Eater's awesome videos for technical details.

TLDR: PS/2 sends separate key up and key down events, sequentially - like #1 Down - #2 Down - #1 Up - #2 Up - each in separate message, allowing for theoretically infinite rollover (excluding certain edge-cases). USB, on the other hand, polls only for keys being pressed at the moment. By default, the keyboard responds with a 8-byte message, with 1 byte being the bitmask for 8 modifier keys (4 on each side), a spacer, and 6 bytes/slots for identifiers of keys being held down. If one identifier is present in one response but is missing or replaced in next one, the system assumes a key-up event. It is possible by USB spec to negotiate connection in such a way that the keyboard responds with a bitmask for every single key it has. But this is not well supported by things like BIOS and KVM's, so very few keyboard manufacturers bother implementing it. Most keyboarrds advertising NKRO are actually only capable of doing so via the PS/2 adapter.

Love that band. Their latest album is the shit.

Second, even if we were to produce hydrogen from water, the cycle of electrolyzing, transporting and using hydrogen is associated with enormous energy losses, and we still have to get that extra energy from somewhere

Is it worse than hauling enormous batteries, though? I know hydrogen looses like half the energy on generation, but to me it sounds the same as if we do all-electric and spend the same amount of energy for just moving the batteries around. I'm too cooked atm, but is anyone up to do the research/math on this?

There's an OS you might like. It has no UAC, no file permissions, no sudo nor chmod, as it has no multi-user support, no antivirus and no firewall, no protection rings, not even spectre/meltdown mitigations, and most of all - no guard-rails whatsoever: You can patch the kernel directly at runtime and it won't even give you a warn. And yet, it is perfectly safe to run. It's called TempleOS and it achieves such a flawless security by having no networking support whatsoever and barely any support for removable media. If you want a piece a software - you just code it in, manually. You don't have to check the code for backdoors if it's entirely written by you... only for CIA at your actual back door...

payments/transfers would be both much slower AND much more expensive than via a bank

Not necessarily. You could have a federated system, where only big players like banks participate in larger blockchain, like banks already do with forex and wire transfers and pay ridiculous fees to clearing agencies, and clear out local transfers locally, possibly inside their own smaller and much faster blockchain.

¿Por qué no los dos?

I know a place where they still do this. They've got an 8-digit user count, 7 digit monthly profits, all running on one server that costs something like $20 a month. They've downsized a few years ago to single-digit employee number and just sit there and collect profits. And this is why I'm now working for a company that casually dropped a few grand for a glorified CPU usage meter and a few grand on top of that for deployment tool that does the same thing that the old guy at a former place was doing with his trusty FTP client.
