Henry Legg @henrylegg.bsky.social · 07/08/2026Zulfi Alam, Microsoft's Quantum VP, says that "this paper thing is kind of boring now".

Henry Legg @henrylegg.bsky.social · 03/06/2026It's good to see that even the mainstream media are being much more cautious about Microsoft Quantum's latest claims. Although, that said, a "practical quantum computer" by 2029 when you haven't even proven that you have Majoranas or a qubit is not the hardest thing to see through. 041
Henry Legg @henrylegg.bsky.social · 02/06/2026Today Microsoft announce "Majorana 2", claiming they will build a “practical” quantum computer by 2029. This is of course massive PR bullshit. I could also speculate about the timing of this announcement, but unfortunately that will have to wait. For now, let's look at their preprint. 🧵 1/x 1336

Henry Legg @henrylegg.bsky.social · 19/02/2026Am I the only one that vehemently detests the phrase "curiosity driven research"? It conjures this image of a toddler asking "why, why, why?"

More difficult for governments to say "we're cutting foundational science". www.nature.com/articles/d41...nature.comDon’t deprioritize curiosity-driven researchAround the world, governments are demanding that research funding follow broader political priorities.
