I'll probably be proved wrong, but doesn't seem that likely (or at least desirable) to me. Unlike seatposts and shifters when we just want to hit a button and have something happen, with braking the feedback through the lever is really important to balancing traction. Replicating that with electronics makes things way more complex, and is still unlikely to ever produce close to the same feeling.
I'm thinking here about cars and fly by wire stuff, that even at it's best never feels even close to as good as well engineered mechanical solutions. For instance, any car I've driven with power steering has given significantly less information through the wheel than good unpowered steering, and I've never driven a car with electric power steering that didn't feel like a (bad) computer game.
