Google warns quantum computers could hack encrypted systems by 2029

How long before Bitcoin's security is broken?

About 2.3 to 4 million Bitcoins are considered "lost".[1] This is several times larger than the remaining 1.3 million un-mined Bitcoins. Expect substantial resources to be devoted to this.

I clicked on the clickbait for you:

"Leonie Mueck, formerly the chief product officer of Riverlane, a Cambridge-based quantum startup, said Google’s statement did not necessarily suggest there would definitely be a working quantum computer capable of breaking encryption by 2029."

Basically more worried about decrypting currently stored, encrypted information with a future quantum computer. My guess is most critical encrypted files use symmetric encryption (e.g. AES256) and won't be cracked with a quantum computer any time soon (or really, ever.)

oh no, it's the end of the computerized slave society, whatever will we do. just imagine having to pay with cash or coin at a physical location and experience genuine social contact.

I'm kind of looking forward to it.
