I'm thinking what this means to gas car makers. Wave 1: "It's all about legacy and prestige, not speed/acceleration". Wave 2: "The track handling isn't all that good, how can drivers take that corner at full power without losing traction". Wave 3: "Alright, we will go electric too".
The best combination is ultimately both though, hybrid systems are already used quite frequently in everything from LMP1 WEC racers to modern hypercars.
