Comment Reddit is not social media (Score 2) 54

Reddit is not social media; it's a message board. Nothing so similar to 1980s UseNet can be considered social media, which debuted in the mid-2000s with MySpace (though the term "social media" wasn't even coined until the launch of the second such example, which was Facebook).

The difference between Reddit and social media? The latter puts profile and pictures at the core, whereas they are incidental in the former -- both used only to support the primary purpose which is text-based discussion.

Comment Definition of "boom" (Score 1) 92

The article seems to define "boom" with this sentence: "The golden age--and middle-class prosperity". If that is the definition of "boom", I wholeheartedly agree that mid-century U.S. was a fluke that unusually benefitted the middle class, for the very reasons stated in the article. However, if by "boom" is meant corporate profits (as one might assume by reading only the headline), although it would take herculean effort, it is not totally impossible that the U.S. will once again become a major manufacturer.

Comment 30 million yottabytes (Score 2) 30

Willow can mutually entangle 105 qubits; this is not like IBM's Condor with 1121 qubits where it is suspected only a dozen or two qubits can be mutually entangled.

The internal state of 105 mutually entangled qubits corresponds to 2^105 * 2 (for phase & amplitude) * 3 (bits per analog value, akin to SSD TLC) = 3 * 10^31 bytes = 30,000,000 yottabytes.

Notice that I said "internal state". Reading those values out is the challenge, usually involving re-running the same program over and over to get a probability distribution. Once you measure, all the quantum states collapse.
