I took the cerebral valley event data to see growth of events. 
75% of events are in SF proper, the second location is in Palo Alto (4%). This was plotted on Aug 22 which includes future Aug events. 
I predict the amount of events will decline in H1 2024, as market starts to consolidate and shift form "formation phase" to "acceleration" phase. 
However a few mega-events will emerge, and hosted at Moscone center for 20,000 attendees.  
On average, I attend three AI events per week.
