I for one liked it.
Watched Nostalghia yesterday :)
Some fundamental questions, but we'll never be able to find an answer.
What is a function: It's a set of tuples where every tuple (x, y) means: x is mapped to y. Of course there must be exactly one tuple for every "x".
(Tuples btw are usually a short notion for {{x}, {x,y}}. They exist always by the axiom of pairing. By the axiom of extensionalty, they fulfill the universal property of pairs, i.e. (x, y) = (z, w) iff x = z and y = w.)
Assume x is a single nonempty set. Picking means: Finding a function {x} -> x. But this is easy: ∃y(yϵx) because x is nonempty, and then we can build our function, which consists just of the single tuple (x, y).
It also works for finite sets of sets since you can do it manually n times, the formula just gets longer.
He IS an easy enemy in this regard, not only to the left. All his (mis)behaviour, naming his child like that, manipulating currency rates through tweets, that's not exactly what average people could afford. If he didn't fit this stereotype of billionaire, I'm sure he would be liked more.
At least Biden seems to be a supporter of the railway. But it could go faster if you'd build tracks instead of tunnels with Teslas.

It would be much more effective to use bicycle and trains wherever possible, and drive small cars otherwise. But wait ... that's not luxurious enough. Saving the world is just an excuse for cool cars.
