In many instances removing or repurposing lanes (road diet) decreases congestion much more effectively than just adding capacity.
Congestion occurs naturally regardless of capacity due to fluctuations in flow (jitter) more often than being over capacity (this is civil engineering 101). By repurposing lanes for dedicated turn lanes, bus lanes, bike lanes, and/or pedestrian walkways, you remove many of the triggers for jitter.
Synchronizing traffic (connected autodrive?) would do much more for removing congestion than just adding high over head capacity.
Chipmaking is not a high labor industry (other than during the building of plants).
China's one big advantage over other work forces is massive amounts of labor that can be directed by central planning. As their labor costs have gone up, labor intensive manufacturing has already started shifting away. When population declines cause labor costs to go even higher, they lose their advantage.
Massive immigration (on a scale never seen in human history) would be required. I don't see that happening with one of the most xenophobic cultures on Earth.
This isn't a problem confined to China, they just have the worst numbers. The entire "first world" is facing declines of varying degrees.
This coupled with climate change is why immigration policy is probably the single most important thing for most countries right now.
The hotness we are seeing is smaller 'expert' models with an 'orchestrator' model in front that evaulates the prompts and routes to the appropiate small models and then synthesizes the collected answer. Easier to split across many smaller, cheaper servers and more efficient than a huge monolithic model.
