The AI boom on San Francisco's buses

I ran past the San Francisco bus depot early one morning and saw almost 100 buses, all splashed with AI advertising. It's epic experiencing the city in a boom.

I found it very funny to see the breadth of AI products on bus advertising in downtown San Francisco.

I ran past the bus depot early in the morning yesterday and took the photo here of almost 100 buses, all with AI advertising splashed all over them. San Francisco has always been a boom bust town. It’s epic experiencing it in a boom. I lived here for five years and in retrospect it was between the dot com bust and the GFC bust ;)
