So only film cameras are slower than Sony FE cameras, then. Okay.
I would come to a different conclusion from what was said.
Film cameras are usually faster than digital for 36 shots, but considerably slower for the 37th. I think this is general, not limited to Sony FE cameras.
I've been photographing since 1968 and went digital in 2006 and have used a large variety of brands and types of cameras (only 35 mm/APS-C, never MF or LF)
In my film days I have missed many opportunities for a shot because I forgot to wind the camera to the next shot or I had to change the film.
Since going digital I have not missed a shot due to a too slow wake-up time of my camera (both with and w/o IBIS sensors), but I have no experience with Sony FE cameras with IBIS.
