Mainframes are as much about uptime as they are processing power. As far as comparing to _ancient_ computers the storage has also increased by orders of magnitudes, both speed and capacity.

Real world- there wasn't a computer in existence that could model the aerodynamics of the spaceshuttle stack in the 70s, it had to be done experimentally in wind tunnels. Today we have video games and web apps that are more than adequate.

Christa McAuliffe was the first stunt astronaut, if that had worked out we would have seen more of them earlier.

I don't remember who said it- seems like Story Musgrave- she had no business on a shuttle flight because she had no idea the danger she was putting herself in. Most people were lulled into a sense of security, but someone with enough engineering to be an astronaut was in a position to comprehend how crazy dangerous it was.

The same is probably true of these folks, but the Falcon9/Dragon combo is considerably safer than the shuttle, so at least its got that going for it.

Wow- that seals it. I said as much up-thread, but its pretty clear: The only places that _might_ be safe are Russia and China, and I wouldn't assume Russia could hold out against NATO retaliation. I'm not talking about 'kinetic war' here, but Article V would require every country that matters except Russia and China to bring pressure on the target.

And are impossible to falsify*. Imagine if the entire economy ran on bitcoin- it literally self documents _everything_.

*I mean, if it turns out there is an exploit and they are falsifiable, then their value immediately vanishes.

Since every bitcoin transaction is public there are legit reasons to tumble that aren't illegal. Hiding my purchases from coworkers or acquaintances is legal- as long as theres not intent to defraud. If I'm a business and accepting bitcoin for payment, its 100% legit to tumble before spending, in fact not doing so would give my competitors insight into my operations.

I could see a requirement to report tumbling to the IRS, but it absolutely is a legit privacy issue.
