Here it comes... automatic transmission

As I mentioned earlier, I understand and appreciate that view. But here's another.
Many automatics don't take away from that same driving experience. I can shift gears very quickly and responsively from either the shift levers or paddles. From that point, the transmission picks out the right gear and shifts faster than just about anyone. So if you seek performance, this is hard is hard to match. Except for doing heel to toe foot action, the automatic takes away nothing and makes improvements. I can still shift whenever I like and it's quicker.
The other thing is manuals don't often work for me. My commute to the office takes 45-60 minutes for 11 miles. The automatic allows me to drink coffee, eat, and whatever.

Seems like a lot of effort to just avoid throwing a lever, or pushing buttons to shift.
If it isn't seamless and doesn't just work without input, I don't see the advantage. I know when I'm out on a ride I use a high gear or low gear depending on how I feel right that instant and can't see a bunch of electronics figuring that out better than my brain.

After setting up a computer for different types of rides based on power output, heart rate and any other inputs there may be, and then you need only to choose 1 before the start of your ride. Seems to me it would be an excellent tool for training.

Your first argument is the same argument used every time new technology comes out. Friction shifting? Why do I need friction shifting? I can change gears by turning a lever on my seat stay. Indexed shifting? Why do I need indexed shifting? I can change gears by turning a lever on my down tube. Electronic shifting? Why do I need electronic shifting? I can gears by turning a lever on my brakes. Automatic shifting? Why do I need automatic shifting? I can shift gears by pressing a button.

I just think there are too many variables, namely the "engine" not being static like an automobile, for automatic transmissions on a bike to be of much help. This is entirely different to the clear advantage indexed shifting has over friction or downtube vs. brifters. I question the advantage not because of some luddite-type hold on the past, but I just don't see it working well with a human. Also, if they incorporate some way of switching based on what the rider wants to do at that moment...like you switch a button to go into "stand up mode" I don't see that being all different than just using regular old gear shifters....so question the point. Adding complexity for nothing.
BTW, I love the idea of electronic shifting.

In this case, it appears that it would cause problems by putting you in a gear that you may not want to be in.

Could be something that is sold bundled together with Di2 and a powermeter that you can either have or not depending on mood; kind of built into the system. That works for me...I wouldn't want it on all the time and I wouldn't want it adding any weight or mechanical complexity.
Power meter hub or otherwise that will interface with the system will continue to come down in price as demand increases for the auto shift feature.
The future of Di2 without a doubt and the true benefit of electric shifting. Shift manual or leave in auto for general riding. Further this is the stone age. Algorithms and sensors will be further refined and auto shifting will likely be intuitive in the new 10 years.

I am quitting by saying two things. I love driving and periodically take performance drivinng training. If you think automatics are boring you need to drive a performance car around a track and see how it performs against a manual.

Bikes: are better than yours.
I'm waiting for a shaft drive, alenax, disc brake, CVT, IGH, auto transmission, tubeless tired, electronic shifting, airless tired, race bike with rack and fender mounts at 12 pounds. On that day, I will be Uber Fred.

The Autobike they show-up on Craigslist from time-to-time. They use a set/series of weights that shift when gears based of centrifugal force, I think.

MHO.... I think the evolution of the safety bicycle... has matured to an impasse. Once the iron horse, human powered machine, becomes powered by everything else as well... it loses purpose. If we have to recharge our electric bicycle-devices why not just add an electric motor and recharge the bicycle as a whole. Or... maybe just add a gasoline motor and call it a motorcycle.

But I really do like the modern bicycles too. I have no idea where bicycle technology is heading. I only hope any developments are good for cycling.

Personally I like my cars with manuals, orr the very least an automatic with a manual valvebody. I like my bikes manual, I'd rather have gripshifts than an electronic shifting bike. I'be riden a 3speed electric shift bike before, it sucked, and was slow.

I like it and if priced right would buy it providing it can also be shut off.
I'd be more interested to have software that you can download your recorded ride to and have it tell you how your shifting was.

While there are modes of failure for an automatic transmission, there are modes of failure for cambio corsa, friction, index and electronic shifting. There can only be no mode of failure with fixed gear. As I wrote before, Henri Desgrange was correct.

There are fewer modes of failure with fixed gear, but there are still failure modes. Your chain can still break, your tires still puncture, your BB/hubs can have damaged bearings etc. A poorly set up fixed gear will have as many problems as a poorly set up derailleur system, and a properly set up derailleur system will have as few problems as a properly set up fixie, but with the added benefit of being able to go uphill with 1 wheel turn/pedal rev and down the other side with 4 wt/rev.

We were talking about "modes of failure" ??

I never said the auto wouldn't outperform the manual, just that unless you're racing, so what? If you're driving just for the fun of driving, the manual is much more enjoyable.
