It was a graveyard graph

Nah. At least not as a replacement for USD any time in the near future.

It’s in a weird position where it’s best as very anti-consumer or very pro-consumer implementations.

For example, digital concert or sports tickets sell out to scalpers almost immediately. If they were issued via blockchain and invalidated if resold again it would be extremely difficult for scalpers to continue (like, having to sell a whole physical device or spoof private keys or something). This would eventually make the practice die out, and people could just buy tickets to things without an artificially inflated market.

Conversely, an audio and/or video codec could prevent “unauthorized” devices from playing digital media they aren’t “authorized” to play. This would have quite the impact on the complexity of media piracy. Similar to Steam some time ago, this makes paying money for things easier than pirating again, but is extremely prone to said corporations misbehaving.

There’s also more complex possibilities, like digitizing municipal voting or permanent record keeping on private chains. Most people get confused about these and without a technology and cryptography background, and realistically at least some background in social services or macro logistics, the average person only has scammers and finance bro wannabees to learn from. That goes exactly as well as you’d expect.

Money is just made up in the first place. If instead you mean using it as an efficient way to represent allocating specific physical resources, perhaps. In the upcoming dystopian apocalypse where people still have to go work meaningless jobs to survive while the search burns around them, perhaps using a blockchain for ‘fuel points’ and ‘drinkable water points’ or something makes sense.

But as a general purpose currency it seems needlessly complex, and we already have a needlessly complex financial system. Changing the complexity doesn’t solve enough problems to be worth it.

As a currency? Yes please. Kill it all.

As a niche technology that very few people would otherwise know exists and even fewer would know how to use, but can be surprisingly effective if implemented properly? It’s ok.

We can still categorize a concept, even if the technology doesn’t exist in a useful state yet.

I was just future proofing my comment for things like this: https://youtu.be/_bDXXWQxK38

The DoD? No.

But I think you’re right that all energy forms should be nationalized. The only way humanity can continue to be the dominant species on earth is if we can declare a “war on pollution” and commit to it in the same way we could commit to actual war.

Fission and fusion reactors are really more like in-between renewable and non-renewable. Sure, it relies on materials that are finite, but there is way, way more of that material available in comparison to how much we need.

Making this distinction is necessary to un-spook people who have gone along with the panic induced by bad media and lazy engineering of the past.

Layer 8 issues occur all the time.

Ehhhhh, you’re missing the human element. Humans do dumb shit all the time. You can’t stop someone from reading something with their eyeballs, remembering it in their meat brain, and using their sausage fingers to type it back into something unsecured. Odds are still low of course, but I wouldn’t be so confident.
