That's because a method of solving useful work has not been discovered yet. Are you also incredulous that we don't have flying cars yet and how come Ford hasn't fixed that problem? If you're so concerned, perhaps you should start working on the problem and become the inventor of the next big p2p currency?

I'd be incredulous if someone had designed a flying car made by taping about ten thousand fans together, pointed them down precariously, and powered them with a little nuclear reactor. Also, it didn't make it more than 3 feet off the ground. Then, had many people talking about how the future of transit had arrived. It clearly hasn't and nobody can point to a single reason their contraption is actually better or does anything novel. But they're all pretttttty sure.

I'm not concerned because the problems identified had already been solved with money. You know, the thing already in your bank account.

Ah I see. Perhaps you should check out https://bitcoin.org/en/faq#what-is-bitcoin some of your points are addressed there.

I’ve read that before. The core issues are not addressed or are glossed over as of course that’s a pro bitcoin advocacy site. Bitcoin is fundamentally broken at the lowest levels.

Which levels and how?

A single transaction consumes 600kWh of electricity and yields 95 grams of e-waste -- enough to power a US home for 20 days. [1]. This is projected to increase. It's 700,000 times less efficient than Visa. If Visa alone were ported to Bitcoin levels of inefficiency it would consume 38X the entire world's power generation capacity. [2] It's actively anti-efficient and becomes less efficient as the price scales and as technology improves. It has worse wealth distribution than any banana republic. [3] The PoW system creates a net negative drag on any economy approximately equivalent to a 48% rate of inflation [4]. It's slow, taking up to 10 minutes to process. It's inefficient. It allows payments to terrorists and rogue states [5]. It's built to allow scams to thrive. It's not even anonymous, it's pseudonymous and tools will automate deanonymization if it ever manages to make it through the top few issues, which, let's face it, it won't.

And how does any of that mean "Bitcoin is fundamentally broken"

This is what you get if you want a decentralized currency. Full stop. There is no alternative currently designed or available.

Finally, we agree.

A PoW coin has the same economic impact as a 48% rate of inflation. If that’s what we have to pay to “decentralize” our currency it’s time to stop trying to do that. The burden is not on the incumbent to prove why it’s better, it’s on the new guy.

That’s what we’ve learned from this decade long experiment: it’s just not worth it. Time to put this idea to bed and pursue something worthwhile.
