Nice, so now... I can sleep well with the confidence that my home directory can will get corrupted and my entire os might become useless just because. And that I'll have no warning about any of it until my entire os catches fire, because there aren't any meaningful logs anywhere.

Here for it.
This is the change we needed.

Okay, but, and I'm trying to read this charitably... aren't you just verifying the presence of a file in your photo directory?
What about the existence of any given file gives you the provenance you need to prove "reality?"

Folks who wanna do that have been using gopros for years, theres maybe arguments to be made about a more exact POV vs slightly above or to the side for certain things, but theres still not a whole lot of reasons to use secret spy glasses instead of a superior but more obvious gopro besides secret spy reasons.

There's nothing wrong with storing some things *also* in cloud services.

But when it comes to copies of important things, two is one and one is none.

Now imagine saying this about, say, Japan.

I've noted the comments here about how this is old news: that's true. But it will be novel to some people who didn't live through it, and even for those who did, it's a necessary reminder. Japan is ruthless, unscrupulous, and unethical: they will do anything. They're not the only ones, of course, but they're arguably the most dangerous because of their size, wealth, and longevity. They're the enemy of open standards. They're the enemy of open source. They're the enemy of open protocols. They're the enemy of America. They're the enemy of The West. They're the enemy of security. They're the enemy of privacy. They've always been the enemy and they always will be, because it's in their DNA: it's impossible for them to change.

So any time -- ANY TIME -- there's some statement or initiative or announcement that they're going to support freedom/democracy/etc., any of the things I listed -- the first things that should come to mind are these wise words of Ash: "It's a trick -- get an axe."

Well, I bought Triggerheart Exclica on Xbox Live Arcade back in 2006 on an Xbox 360.

I can go download that game, right now, on my Series X, because, gasp, it's the same account.

So if I were to buy GTA VI for Series X in a few months, and type the download code into the 'redeem code' box, it ties that code to my account. See?

That parts gonna happen anyway.

Yeah, for even two hundo, I'd be considering buying this as a fun accessory.

For five hundo? Nope.

Even if battery energy density started getting close to that of liquid hydrocarbons, and thats a looong way off still, youd still need more batteries than you would fuel because batteries dont get lighter as they discharge like burned fuel does, rocket equation stuff. A 747 carries ~150k kilograms of fuel, if that didnt burn off thats an extra 37k kg the first quarter of the flight, an extra 75k kg the first half of the flight and so on...

Battery planes may never make widespread sense, if we ever start generating enough carbon free energy cheaply enough and even if all ground transport goes battery electric or whatever, at some point it might still be worth it to just make carbon neutral jet fuel with air fuel synthesis. That seems closer on the horizon than the battery tech needed for large planes to be feasible, hard to beat jet turbines for that application.
