AR glasses will hit a wall but passthrough AR will be converged on rapidly. Starting 2022
Any particular insight why 2022? Hololens 2 has shown that it isn't so easy to advance the field. I don't think an Apple device is forthcoming or likely to leapfrog.
Facebook, Apple and others are releasing their first AR glasses then.
For me, the name 'Eagle' reminds me of the book "Soul of a New Machine" by Tracy Kidder. That book is about the design and bring-up of another new (at the time) computer system, the Data General MV/8000, which was also code-named Eagle. I wish IBM great success with their work. edit: Clarified that the MV/8000 project was also code-named Eagle.
Haven’t read that yet but I read “House” by him recently and it was quite good
It is incredibly dishonest of them to post this without any details about the noise parameters of the system. When reading "127-qubit system" you would expect that you can perform arbitrary quantum computations on these 127 qubits and they would reasonably cohere for at least a few quantum gates. In reality the noise levels are so strong that you can essentially do nothing with them except get random noise results. M…

Quantum Computers sitting in their cryogenic chambers are such works of art, stacks of giant brass plates and hundreds of heat pipes (or coolant pipes? liquid helium I suppose) twisted and coiling throughout the structure hanging like some steampunk chandelier (why do they hang from above anyway?) EDIT: changed to a few direct links to pics: [0][1][2] The esoteric design reminds me of the Connection Machine blog post…
They hang from the ceiling because they use evaporative cooling (the high-energy particles escape, and the low-energy particles remain in the bucket), each lower stage a bit cooler than the one above it.

I haven't read anything on this one yet, but your analogy fits Google's “quantum supremacy” paper really well, I likes it.
Ugh, the point is a fine one but it appears it has to be made: Validation of experimental theory through the characterization and control of an entire system is not the same as building the same system and simply seeing the final state is what you expect. The latter is much easier and says very little about your understanding. Here's an analogy: Two people can get drunk, shack up for the night, and 9 months later hav…
The accomplishment is more akin to creating a bathtub with 127 atoms and doing fluid dynamic simulations on that, which is a much harder problem in many ways than doing the 6e25 version of the experiment. But it is very questionable to me whether any claims of quantum supremacy retain validity when leaving the NISQ domain and trying to do useful computations.
Gil Kalai's work in the area [1] continues to be very influential to me, especially what I consider the most interesting observations, namely that classical computers only barely work -- we rely on the use of long settlement times to avoid Buridan's Principle [2], and without that even conventional computers are too noisy to do actual computation.
