I didn't hear about the thrusters. Were they expending accumulated solar energy so it could recharge?

What Voyager 1 uses for fuel.

Quote:

The spacecraft actually carry two types of fuel—one to power the thrusters, the other to keep the electricity humming. The propellant is hydrazine, a simple concoction of nitrogen and hydrogen that smells like weak ammonia. It was chosen—and remains favored today—because it's cheap and has a very low freezing point. The Voyagers' jets are used to orient the vessels; the geek term for the hydrazine is "attitude control propellant." (There's no need for constant propulsion, of course, because space is gravity-free, so the initial boost went a long way; the spacecraft additionally took advantage of the outer planets' gravitational fields, which act like slingshots to increase speed.) NASA estimates that the Voyagers' fuel efficiency is upwards of 30,000 miles per gallon of hydrazine.

2040 - AI will surpass humans.

Projecting 22 years out is foolish in my opinion. Shit is going to get weird (if we make it that far). IE: Transhumanism / Singularity.

Agreed. In 1989 Zemekis did Back to the Future II which showed life in 2015. They pretty much got nothing right.

You'd think that with all of the hype about how historically accurate the BTTF films are, they'd put a little work into it.

*yawn*

Heck, 2001 nailed Ipads.

2001 was just a feel-good summer movie though.
