If you want people to understand that numbers are concepts / descriptions of something potentially infinite, and that it's ok to totally work with non-finite describable numbers without ever really writing out their values, just fucking start with that. I honestly think the start of most undergrad math curriculums should be a logic & foundations class with proofs, sets, number theory and the whole "numbers are more logical concepts, not really specific values" vs. calculus. Then teach calculus, with a big dose of 'what is infinity, really?'.
I think it's actually a great disservice and the hand wave that most calculus math classes do about those exact concepts really fucks over a lot of people. It makes calculus a weed out class because the fundamentals are not explained properly so a good amount of people just go into it as yet another thing they have to ape without real understanding. And for the people who don't work well with things they half understand, they really struggle, like I did. It really made my computer science degree a lot worse, because of the instance of starting all undergrad math with hand wavy calculus, for 3 or 4 classes.
I even wrote blog articles about it, it was probably the worse part of my computer science degree, and if math education was done differently where they didn't handwave, I probably would've had a much better time.

Same reason why it's been a very long and hard road to replace craigslist for many things.
#3 is the real treasure trove.
The underlying issue is the technical failures of video calling, not the social environment it's used in.
Fairly soon everyone will have a smartphone and you can get service for one hour of work a month.
After a certain point it's a language and population thing, and France has a language barrier compared to english.
2.4 ghz tends to be 200mW, and 5ghz max tends to be 4000mW. I wanted to be as pessimistic as possible to still make my point.
Although with stuff like 4x4 MU-MIMO routers or dual network routers with one for 2.4ghz and for 5ghz, you could say it's 4 radios at once = 16W max. Radiation per inch of 4x4W power sources is different than one 16W source, so it's not 1:1.
To compare, your wifi router does a max of 4000mW transmission, which is 4W
The apple watch being held together by glue vs interlocking plate or screws although is something I don't like. It makes the water resistance fail when you are in a hot situation, like a hot sunny day, a warm shower or a hot tub.
And in the USA, you only pay sales tax for customers inside your state, unless you have something called a 'nexus' within the other states, which is simpler to avoid by staying put in a single state.
If it's too big of a number for you, then better remake / recover those records. Luckily you have a permanent record called the blockchain.
I gave up long ago on tech companies serving a 'diet plan' cafeteria line of food, like they may do for vegans or similar.
