Not OP, but we have contractors in Nigeria, and paying them via regular bank transfer is nearly impossible. For example many banks will outright refuse to make SWIFT transactions to Nigerian accounts.
This is just one example of a few factors that lead to a sort of isolation from international banking.
Europe “missed the Internet” (and the US didn’t) because of various underlying factors - smaller/more fragmented markets, a more muted entrepreneurial culture, shallower pools of capital, etc.
I don’t think the fact that Google, Amazon, and Facebook were built in the US is down to EU regulations.
It’s no more difficult to start a tech company in Europe than it is in the US, and it’s generally no more onerous to grow it, from a regulatory perspective. But ambitious entrepreneurs often head to the US in order to tap into a larger market and more developed ecosystem.
So I’m not sure the analogy is that valid. But yeah, I do think that EU regulation of AI may be an additional factor that skews the playing field.
The absolute value of a complex number is defined in a different way than that of a real number. For complex number z it is sqrt(Re(z)^2 + Im(z)^2). GP’s examples are correct, I don’t think there’s any ambiguity there.
Am not the author of that comment, but the fact that comes to mind is that aluminum is used for virtually all transmission and distribution lines - for price reasons - even though copper has better conductivity.
If we did discover a room-temperature superconductor, I suspect it would be a while before the cost to produce it in the bulk quantities required for electrical transmission are economically attractive compared to what’s already available.
