Future Technology[Daily Briefing] Chips hit a wiring wall 🔌 Ransomware hijacks AI coding 🤖
AI's real bottleneck isn't the chip. It's the wire between the chips.
SEMICON Taiwan opened its International Semiconductor Week forums in Taipei today, and the talk of the floor wasn't a faster processor. It was plumbing. More than 100,000 people from 65 countries turned up, and the recurring theme was that we can now build accelerators faster than we can feed them. The copper links shuttling data between chips have become the thing holding everything back.
The fix everyone is pointing at is co-packaged optics, which means putting the light-based interconnect right next to the silicon instead of out on the edge of the board. TSMC's COUPE platform has moved into mass production this year. UMC has turned out its first mass-produced silicon photonics wafers at its Singapore fab with Silith Technology. Foxconn reckons it will start shipping CPO switches this quarter, and its affiliate ShunSin says it can now mass-produce 51.2 and 102.4 terabit parts.
That is a big shift in where the money and the difficulty sit. For twenty years the interesting engineering happened inside the chip. Now a serious chunk of it happens in the packaging: wafer testing, fibre array units, high-speed optical assembly. Boring-sounding work that quietly decides how big a cluster you can actually build.
Why it matters: If optical interconnect scales the way Taiwan thinks it will, the ceiling on model size stops being about how many GPUs you can buy and starts being about how well you can wire them together. That reshuffles who matters in the supply chain, and packaging firms nobody outside the industry can name suddenly become chokepoints.

Tool of the day: Tailscale
A mesh VPN that connects your machines to each other rather than to a central box. I use it to reach my home server from anywhere without opening a single port on the router, and setup genuinely took about four minutes.
Honest take: the free tier is generous and the magic-just-works feeling is real, but you are trusting their coordination service to broker your connections, and if you want to avoid that you're self-hosting Headscale and the four minutes becomes an afternoon. Worth it if you have more than two machines. Overkill if you have one.
Question for you: what's the oldest piece of hardware you still have doing a real job? Hit reply, I read every one.
