"Just finished a one-week trip to China. I've now "survived" all the major (20) L2 self-driving and robotaxi vehicles in both the US and China. Some thoughts & observations: L2 self-driving I tested major brands like $Huawei $Li $NIO $Xpeng and $Xiaomi. Overall they exceeded my expectations. The rides were not overly cautious and handled complex situations (yes road conditions in China are very challenging) quite well. Nothing compares to $Tsla's approach. I see imitation learning/end-to-end as the only effective approach for self-driving. While Chinese peers perform well on main roads they"

Total ad spend grew roughly with GDP but onlines share went from X% 70%. e.g. Today U.S. ad spend totals about $380B/year XX% of which ($260B) is online. Within that $Googl's U.S. ad rev is roughly $140B; $Meta's about $70B. Ads = X% of adjusted PCE meaning that on average U.S."
