No, a leather-clad singer who lives just down the road from here.

You live near Suzi? You lucky boy.

Yes, there are automatic shifting systems like Shimano Di2 with Synchro Shift or Enviolo's CVT hubs that adjust gears based on speed or cadence.
I’ve tried one and it’s super convenient, especially in city riding where you stop and go a lot.

So the front mech killer failed to kill the front mech. I am surprised.

Well and truly bindun.
Sachs DualDrive and Sturmey RF3 both near-enough replicated the ratios of a triple chainset using internal hub gearing. Assuming you use a 40T chainring, the hub gives you the equivalent of a 30/40/53T chainset, very close to a Shimano road triple of 30/39/50T.
