people will be complaining about the "energy waste" in the current AI craze after hauling their butts around in 3-ton metal cages for decades, a lifestyle that is enabled by paving half the planet in tar.
But hey, if my metal box is an EV, I can at least pretend to be part of the solution while doing nothing, partially paid for by other people's money.

Violent extremists like the Minnesota shooter are not lone wolves

The lone wolf metaphor used to describe mass shooters misinforms views of extremists – and hampers law enforcement efforts to deter the violence.

Republicans: Book bans, forced births, guns in kindergartens. Democrats: Health care, voting rights, student debt relief. One party wants a future. The other wants revenge. It's not complicated.

The Minnesota shooter who killed state Rep. Melissa Hortman and her husband wasn’t a lone wolf, insists a scholar of political violence and extremism.

Violent extremists are almost always part of broader networks. The myth of the isolated madman obscures the networked reality of far-right violence and makes it harder to prevent the next attack.

I've had a secret theory for a while that I guess I'll just throw out there: The right is inevitably going to turn on AI, not because LLMs hallucinate or get things wrong, but because they mostly *get things right*, and reality, as a great man once said, has a liberal bias.

@web3isgreat seems only tangentially related to crypto

@web3isgreat I was wondering, how do they destroy cryptocoins?

It's explained in the article. They created new wallets with "vanity addresses". I guess these can be used if you reverse engineer a private key, but that's "computationally infeasible" unless the vanity address is short. Since these were quite long textual political messages, we know they "would not have the private keys for the crypto addresses they sent the funds to", so the money is stuck in those unreachable wallets forever 🔥

@harry_wood @web3isgreat With Bitcoin it's the "script" of the previous transaction that determines if the new transaction is valid.

Often it's a simple "if you can prove you can sign something using the correct private key you're clearly the owner" but can have any kinds of conditions

It's easy to create a script that has impossible conditions, making it provably impossible* to do anything with those coins.

(*unless 51% of the nodes start to accept that script, but then all bets are off)
