It's possible to guarantee exactly-once delivery, just not in bounded time, but eventually. That's what FLP impossibility is about, impossibility to achieve consensus (e.g. exactly-once) in bounded time. But if you are talking in the context of semantics, it's a totally different thing, it's a computation model and it's absolutely possible to have exactly-once semantics, regardless whether you achieve it by waiting, like consensus-based systems, or by using special data types and operations that can be performed without waiting and eventually converge, like CRDT systems.
Morality doesn't exist outside of "socially prescribed conclusions", it's actually a pure social thing, it has no other function, but to help individuals make socially acceptable choices.
Children can reason morally and do, they just didn't learn a lot of morals to reason with yet. Morals, i.e. what is good and what is bad, is something people never stop learning. Obviously learning moral values from cartoons isn't helping in situations with real people.

That would be system programming, part of computer engineering actually [1], not software engineering. Also software engineering usually does include some computer engineering.
From one perspective types (and I mean proofs encoded in types) is a compile time measure against bugs, while supervisors is a runtime measure. It's much easier and more productive to not do proofs and rely on runtime architecture for reliability, it adds relatively little complexity and asks very little from developers, it stays almost the same as regular software development. And it's still necessary to do regardless whether you have proofs or not.
And types like machine types are of course irrelevant for BEAM, well, maybe they'll start to matter a bit with JIT, but probably still not, BEAM with JIT is still not going to be a performance miracle.
Right, but the point is those materials are not for starting a sustainable business, but a startup, a whole different thing as you understand. For sustainable business you probably don't want to listen to anyone involved in VC-funded startups, it's in their interest even to sabotage you.
It's also not random. I've talked a couple of times in my life to strangers in public transport, well, they actually talked to me, both times somehow accidentally people who I talked to were IT professionals, one was a programmer, the other one was a sysadmin and it was in the 90s in former soviet republic, hard to randomly encounter such people back then.
You should read some Nassim Taleb or something, because what you are saying is too nonsensical, like there is no awareness of chances in your arguments whatsoever, as if this dystopian concept of merit is somehow actually real.
It's not ironic, such dystopia is particularly liked and promoted by capitalist scumbags, because it lets them justify exploitation, inequality, overwork, etc. But of course for any thinking person it's obvious that it's an awful awful idea, as if a kid raised by well educated parents who can therefore do really well in school deserves more, than a kid raised by uneducated parents who have no idea how to teach kids to do well in school.
It's "strong" in that you can see some effect in blood of people tutoring vs people waiting. But that's about it, you can't draw other conclusions from it. It says absolutely nothing about volunteering, health, being kind, etc.
How on earth can they control for that in short term studies? Is it even possible to get any statistical significance on that? Smells like bullshit, there is no way there is causation on health from volunteering.
Think about it, if you are volunteering you are likely to not just have good health, but afford good health care, have plenty of free time for various activities, less stress in life, enjoy and seek social activities, outdoor activities, etc. All those things could impact health, but not volunteering itself.
