Not sure what you mean by feeling disconnected from the bike. Push a button or shifter and it shifts. My shifting is smooth on all my bikes (shimano slightly smoother than SRAM) but changing it over to electronic would not change how it feels.
With that said, I'm not planning to go to electronic shifting anytime soon. Maybe I'll change my mind later. On friends bikes-e shifting I have already seen batteries die and software/electronics malfunctions already for those that have it and then they can't switch gears. Plus it's one more battery that I need to worry about charging up. I already have cell phones, chainsaws, bike lights, watches, weed whackers and bike computers to charge up. I don't want one more item to worry about when cables work just fine.
Maybe I'll change my mind in the future. IDK.
