In the "proof" presented, the series 1-1+1... is "shown" to equal to 1/2 by a particular choice of interleaving of the values in the series. But with other methods of interleaving, the sum can be made to "equal" 0, 1 1/3 or indeed AFAICT any rational number between 0 and 1.

So... why is the particular interleaving that gives 1/2 as the answer "correct"?

"Powerwall" is just a big battery.

Yes... plus some electronics, like a rectifier, an inverter and control circuitry.

It might help compensate for the irregularities of solar and wind power.

Yes... that's partly what is was conceived to do. It also can compensate for the irregularities in demand.

But it only makes sense to use batteries for that after we have moved to much more renewables.

For storage of solar and wind power, this is a complex matter, and the short answer is "it depends". For demand management, it makes sense now.

It is much more efficient to store the power in the water magazines of existing hydro plants.

It is desirable to use hydro plants (where they exist) as swing producers. Pumped storage is not quite as energy-efficient as battery storage (roughly 75% for pumped vs 85% for Li batteries), though it can be cost-effective, in places where large, elevated reservoirs already exist.

But all this is besides the point, which is: There are proposals to "solve" global warming, which are implementable now, with today's technology, which furthermore have side effects which are on balance positive (like clean air in the cities).

Despite his frequent comments that he's "betting" on Trump and that Silver is "betting" against Trump, Adams's position is that gambling is illegal when pressed to actually bet.

How convenient for him.

Well... Scott Adams has a lot of money. I am willing to bet that Trump will NOT become president, at EVEN ODDS. Scott, if you read this, how about a wager? I propose a $10,000 stake.

If you are after descriptions of society in those days, try "Quo Vadis" by Henryk Sienkiewicz. Historical fiction about early days of Christianity, won a Nobel Prize for literature. Strong religious themes.

Or could we breed them for intelligence...? With such short periods between generations, we could reach superintelligence, maybe faster than other methods!

The Big Lebowski: "Yeah, well, you know, that's just, like, your opinion, man".

What are my options apart from "emigrate and live next to a cryonics facility"?

You could start a cryonics facility in South Africa.

Gets a big loan from Russia that prevents an economic collapse (20% likely)

I'll give 10:1 odds against this happening. Russia has its own economic problems now with the drop in the price of oil and Ukrainian conflict, and other issues... China might be more likely, though IMO both Russia and China are a scare ploy by the Greeks.

A somewhat likely possibility is: Greece leaves the EU, triggering an economic collapse, possibly followed by a political collapse. Then spends many, many years trying to sort out itself and wishing it had stayed.
