Same, but then again, I still don't understand the appeal of automatic transmissions in cars (despite that being all I own these days). I generally prefer simpler machines with less stuff that can break.

Bicycles should be extremely simple. You pedal to go, and if you want to go faster for the same RPM, you push the chain up a gear. If you have gears in the front and back, you shift the front every few times you shift the back. That's it, that's all the complexity I need in a bicycle.

What happens if you're out on a ride and your battery dies? You just can't shift anymore? That's terrible! Or what if a thief steals your fancy electronic shifter? What if the SW goes bad and the pairing breaks? There's just so much that can go wrong, and not a lot of backup options. If my derailleur gets messed up on a ride, I can probably still use a handful of gears, enough to get home. If a shifter breaks and I have tools, I can adjust the indexer to keep it in a decent gear to get home. It's like that manual transmission, if something breaks, I can probably work around it.
