its weird because its not like cars where manual shifting is simpler mechanism and easier to fix. in the case of bikes electronic shifting (modern ones like sram axs) are actually more simple of a solution/mechanism if you think about it.

I still drive a manual transmission car though lol. I just like the engagement and zen like motion of looking ahead at situation knowing when to clutch and gas even in traffic.

But for my next road bike I'm going electronic shifting... i learned how to wrench and assemble bikes myself and loved it but don't want to deal with that anymore if I don't have too. Upgrades are as simple as just installing a new RD/FD and synching it and you're good to go.

installing hydraulic disc breaks compared to rim brakes on the other hand....
