I haven’t gone electric shifting because of cost, I haven’t gone electric shifting because its a proprietary system that relies on the good will of the company.
Make it open source and I’ll jump.
I’m sticking with cables, no need to charge them lol
I also think the wireless bit is pointless (particularly with ebikes), just 2 more batteries to worry about and probably some app I’d rather not need. Even with a folding bike, I don’t really care if there’s 1 less cable (though digital would mean more freedom with cable routing).
A cable-actuated derailleur that could sense if it were out-of-tune (especially if it could tell you exactly what needs adjustment by exactly how much) would probably be enough for me.
Too rich for my blood but kind of a neat retrofit.
