I might be holding it wrong, but last time I tried to use DynamoDB it made absolutely no sense performance-wise to me. Postgres on my laptop was many orders of magnitude faster for fraction of price. It seemed like it maybe might make sense when you hit multiple TBs of database data and can no longer run on a single server? But then the costs would be sky-high and you probably could engineer your way around this with this kind of money.
There is a way to look at mathematics as just a bunch of rewrite rules for things on paper. It might not be particularly inspiring, but it's a valid way to look at things.
Besides "secret" knowledge like the know-how at jobs, there's things like unwritten social etiquette (especially as it varies from place to place) or interfacing with physical world – reading about chopping tomatoes is different from experience acquired by actually chopping tomatoes.
Historically aristocracy was the military class. Nowadays in authoritarian societies it looks like it's mostly matter of time before military takes the lead.
Never had this issue with several cellphones I had in ye olden times when all cellphones had removable batteries. All it takes is a properly designed connector.
I think that CT is more akin to just a different language for mathematics than a solid set of axioms from which you can prove things. The most fact-y proof I've personally seen was that you can't extend the usual definition of functions in set theory to work with parametric polymorphism (not that just some constructions won't work, but that there isn't one at all).
For example all the quantum computing is reversible and really doesn't want qbits to interact (hence get any energy) with the outside. So if you ignore all the supporting apparatus in theory it could work without spending energy. Toffoli gates can be used/realized in quantum computes.
Like there was any chance to see UX of this to work or not in most of places. I've never had an ISP that even offered any IPv6 connectivity besides mobile internet.
On x86/x64/variable instruction length architectures this isn't always the case. You can jump in middle of an instruction to get a different instruction. It can be used to obfuscate code.
