China was a really backward country 50 years ago. I expect that China has paved a lot of roads which are still in good shape. Europe by contrast has had paved roads for a long time and those older roads via normal wear and tear are wearing out. The question then becomes when do you patch, recover, or replace - this is in order of both cost and how nice the road is after. Give China a few more decades and their roads will become less smooth because it isn’t worth the cost to make them perfect.
They make that impossible. they track surveys of how much ai helps - but the lowest grade possible is 0-5% improvement. No way to mark that it cost me time vs writting code by hand. If you can’t measure it you can’t improve it - and they are not allowing measures
