Leadership in the Era of Quantum and AI – A Reaction
This lecture was framed as leadership in a time of economic, social, and environmental crisis. In reality, it was a performance, a ritual reaffirmation of the system that generated those crises. A talk about “leadership” steeped in the language of inevitability, technological salvation, and corporate myth-making.
The speaker, Muhtar Kent - Coca-Cola executive, delivered a brand sermon for the young acolytes of the #deathcult. Unconsciously or not, he was selling the two current hype […]

@cstross @skjeggtroll Moore’s Law is dead for now. I did a study a few years ago to look at what is happening and will happen in microprocessors. Short story is that traditional processor architecture is hitting end of life. Feature sizes are so small now that quantum effects are a significant factor. High speed and small size also means we are up against a thermal barrier as well. Clever approaches with System-On-a-Chip ( #SOA), 3D stacking, maybe Processor-In-Memory ( #PIM) and distributed multiprocessing will squeeze out more progress for maybe a decade. After that comes the next computing revolution — a shift to non-Von Neumann #computing. #Quantum has the spotlight because that’s the really big win, but there are other approaches that are likely to be commercially viable before quantum is mature. I’m optimistic about the tech, less so about the rate of adoption and change that will be required, especially if the most talented early- career computer scientists and engineers keep chasing the associative/statistical methods that include LLMs.

@skjeggtroll Of course it will. It's the consequence of the taper-off of Moore's Law rippling through the consequential supply chain it propped up for 50 years, ie. semiconductor products reliably doubling in performance every 18 months. That's now slowed to a trickle and they're squeezing the last drops out of the toothpaste tube of optimistic investors:

I like watching popular science type videos. Everybody who tries to explain quantum mechanics always uses the word "collapse" and they always pull it out of nowhere and make no effort to describe what the hell they're talking about. Why is this? Are they being paid off by the dictionary people to use specifically that word or something? Do I have to actually learn physics if I want to know what's going on here?

Large language models are quite useful to perform searches through the literature, so you have a good point to start. So, this is what I just got asking ChatGPT for references for the numerical calculation of the replica correlation lengths in topologically ordered systems:
1. Pizorn & Verstraete (2010):
Title: “Topological entanglement entropy in PEPS”
Journal: Physical Review A, 81, 032307 (2010).
DOI: 10.1103/PhysRevA.81.032307
2. Orús, Wei, Buerschaper, Van den Nest (2013):
Title: “Geometric entanglement in topologically ordered states”
Journal: Physical Review A, 87, 042328 (2013).
DOI: 10.1103/PhysRevA.87.042328
3. Schuch, Pérez-García, and Verstraete (2010):
Title: “Classifying quantum phases using matrix product states and PEPS”
Journal: Physical Review B, 81, 024451 (2010).
DOI: 10.1103/PhysRevB.81.024451
4. Schuch, Cirac, Verstraete (2011):
Title: “Classifying topologically ordered phases in 2+1 dimensions using matrix product states and PEPS”
Journal: Annals of Physics, 325, 2153-2215 (2010).
DOI: 10.1016/j.aop.2010.04.003
5. Pizorn, Verstraete (2010):
Title: “Topological entanglement entropy in PEPS and tensor networks”
Journal: Physical Review A, 81, 052324 (2010).
DOI: 10.1103/PhysRevA.81.052324
Very nice! Well, until you realize that all five references are totally made up and the provided DOIs are either 404s or go to completely different papers.
I feel being snarXived.

Inspired by #Schrödinger I have maybe got a non-lethal solution to Australia's #feralcat problem.
If we put out a very large number of cardboard boxes...
