Spoilers: it won't: noisy neighbours, congested bands, and actual real world mean getting more than what we are already getting is next to impossible. Because basically those same factors are holding back even top speeds of wifi5, nevermind 6/6E

Raising the maximum possible raises the average as well. Not at the same rates, but there will definitely be improvements in the less visible bits like error correction, accounting for echo, etc.
Call me sceptical then. We're pushing Shannon's law essentially already

You're sceptical! 😁
I've not heard of Shannon's law, but if you're referring to Shannon-Hartley theorem then, from my brief understanding, wifi 7 will still bring improvements in bandwidth purely from doubling the channel width. Doubling the number of antennas is probably not going to affect home users as those will probably be prohibitively expensive, but enterprise might snatch it up - who knows.
Increasing the antenna availability increases available airtime in a given band, reducing the airtme 'load' of IoT and similar devices on the spectrum. This alone would be a dramatic improvement, but increasing the modulation by a factor of 4 should dramatically reduce airtime utilization for normal client loads, regardless of available upstream bandwidth, resulting in more airtime for everyone else and dramatically improving wifi performance in congested environments, assuming access points are designed with sufficient memory to allow for buffering frames in this manner.
Wifi7 should be as big an improvement as 11b to 11g, assuming the hardware vendors don't shit the bed on it.
