I don’t think this is going to happen, but: It would be extremely funny if Apple strapped a heavy copper heatsink and a turbo fan to an M1 and just overclocked the ever-lasting crap out of it.
The crazy thing about using a Macbook Pro (with an M1 Pro or M1 Max CPU) is that, in single-threaded performance, it's really no faster than a dippy little Macbook Air. And at the end of the day, single-thread performance is more effective than multicore! TBH I think this tradeoff is the right one (that is, not overclocking Macbook Pros), but when the iMac Pro and the Mac Pro roll around… why not? Just go for it.
