Fujitsu to begin first AI semiconductor exports next year — TSMC to manufacture the chips The headline needs a step down. This is not a GPU or a dedicated NPU. It is FUJITSU-MONAKA, a server CPU on Armv9-A. Successor to Fugaku’s A64FX. TSMC 2nm compute die stacked on a 5nm cache 813 views · 1 likes · 0 reposts · 1 replies Open on X →

Korea had Robot Taekwon V People often treat the US and China as the two giants of robotics, and Korea is frequently described — sometimes with self-deprecation — as lagging behind. But I still remember an assignment from a Control Systems class I took more than 30 years ago in

X regulars already know the gold Cybercab. Most people still don’t. A 61M-sub YouTuber sees one in Texas and can’t believe there’s no driver. I photographed a prototype in a Silicon Valley parking lot and my wife asked what I was doing. I said "It is a Cybercab". She asked

I’ve spent nearly 30 years in the semiconductor industry as an engineer and engineering manager, mostly keeping my head down and just doing the work. That’s also why I ended up staying on X. Back then, when someone asked “What do you actually do?”, it was hard to explain. In the

Yep, I'm personally high conviction on the AI trade (especially photonics/memory) despite macro. - $NVDA gave forecasts for $1.3T hyperscaler capex ($100B+ above BofA analyst expectations) - $SPCX Wells Fargo forecasts are ~$263B for 2027. - $127B spend in 2027 for 409.4K views · 1.3K likes · 94 reposts · 101 replies Open on X →
