This. This is a legal earthquake and existing law firms will pivot and new law firms will be created to dive into Big Tech social media settlement money. Plaintiffs will be groomed, "expert" witnesses will be retained for years, judges will get cushy property deals and non-show non-profit jobs for their clans.... the whole shebang is spinning up right now.

And "changes" will only mitigate (no preclude) future cases. This is all unprovable mental health stuff and "harm" can be attributed to anyone that's seen a post since facebook et al. was founded.

Altman and co. are dealing in investments of 10s and 100s of billions of dollars. Disney comes to the table with $1B and expects what, exactly? That OpenAI will be the firewall that protects Disney from AI predation? LOL. Disney will need to 10x or 100x that number at least, and they're still going to lose.

The first fission reactor in space, the American SNAP-10A had an experimental ion thruster.
The Soviets launched dozens of nuclear powered satellites, but again, thrusters were only used experimentally.

So while not actually "the first nuclear powered interplanetary spacecraft" (RTGs win that) it is the first nuclear-powered rocket in space, aside from small experiments.
With only 2N thrust, it is no use below LEO, and solar power is plenty good enough for ion-drives in earthly satellites. So nuclear-powered rockets are only useful for interplanetary missions, for now.

You've answered your own question. Don't turn it on until safely in orbit.
  Usually that sort of question comes from people who don't understand that reactor fuel is barely radioactive (only the waste).

Compare this to what you would have said last year.

If only you could get to Mars by burning investor capital and government grants.

It was male. However, it was also gay, as Colbert will reveal.

Gay elves, gay hobbits. You'll see.

There will be female elves beating up everything: orcs, male elves, male humans, dragons, horses, barrels of ale. Everything.

Also, girl Legolas. Bet that.

Might have made a good date movie, if anyone still went on dates.

Somehow "cheap weapons able to target civilians, but not those well protected" doesn't make me feel happier. And such weapon are clearly only useful for attack, not defense.

Well, arguing from the derivation of the word is just silly, but:
https://founders.archives.gov/...
clearly shows that some of them agreed with that point of view. Hamilton, however, was only one side. Others interpreted it differently.

Actually, all that literally means is that you can carry them. It doesn't say anything about ownership or control.

Calling that a deterrent is whitewashing it. A hypersonic missile is an attack weapon unless it is specifically an anti-missile missile. It's most highly useful in first strike situations.

Actually, it's one thing to announce, it's another to manufacture at scale. If this is real, it will be a severe threat in 5 years, perhaps a bit less.

What's the range? I really doubt that this is the new MAD, but it does add a new and exciting amount of uncertainty, and increase the advantage of attack over defense.

"Well regulated" is not well defined. It definitely didn't originally mean "government approved"...or at least it didn't mean that to everyone who put their signature to it.
