Emulating RISC instructions on an x86 is typically much easier than emulating x86 instructions on RISC. Particularly if you have to emulate the clunky, convoluted PC hardware, too.

"In use the Archimedes PC Emulator program gives quite acceptable performance if you don't want to go too fast. While the hard disk access is extremely fast, the computing speed is only average and the screen display speed is slow."

And it gives the 'computing index' performance as about 1/10 of an AT PC. That's pretty much my experience of PC emulators; for apps that spend most of the time waiting for user input, it's fine, but anything that requires real computing power needs a CPU that's about 10x the performance of the CPU you want to emulate.

Most radiation can be stopped with shielding--which won't be a big deal on a spacecraft big enough for humans to live in for decades or centuries--and humans with lifespans measured in centuries would require much better genetic repair mechanisms than we do.

And I'm sure I read an article recently about researchers increasing the radiation tolerance of cells by a factor of 1,000 or more by boosting the repair mechanisms.

Exactly. Life extension will be required to colonize the galaxy, if we're forced to use slow, sub-light spacecraft that require decades to centuries to reach the next star.

So they'll keep voting Democrat.

When they stopped being radio controlled. There are plenty that can be programmed to fly specific courses via GPS and left to their own devices.

Why do you think the person targeting the Killer Drone even has to be in the same country, let alone the same city?

There is no solution to this problem that involves restricting drones, because that won't stop the bad guys. The only solution is to ensure the Killer Drone can't get to your high-value target.

And how long do you think that law can last when every tourist has a selfie drone? You're really going to arrest all of them for flying a one-ounce drone with a range of a hundred feet?

Yeah, because someone who's determined to kill a politician will be scared off by the idea of being jailed for flying a drone near them. Meanwhile, in ten years, every tourist in DC will have a selfie drone, and companies will be renting drones so people can 'visit' remotely over the Internet. How many of those do you plan to lock up?

The real solution is simple and obvious. In future, politicos will just have to live in sealed, underground bunkers.

Given an infinite lifespan, everyone would get to be the richest man on Earth for a while. And the poorest.

Because the left hate humans, because most humans won't do what they're told just because the left are convinced they know what's best for them. Also, humans typically move further to the right politically as they grow older, so a population whose average age is measured in centuries won't have much time for SJWs.

People who think touchscreen controls are a good idea in cars have never tried driving one at forty below zero.

That would be true, if the voice recognition actually worked. I typically have to try at least a dozen times to get my car to dial the right number on my Bluetooth phone, and even saying 'Redial' to dial the last number can take four or five tries before it does the right thing.

And your problem is?

Why should poor people be funding scientists to carry out research that costs more than the benefits?

When was that?
