They dont work well because they dont know when you need to shift, and they dont shift very smoothly. Since the invention of index shifting, which makes shifting easy for inexperienced riders, there is no need for autoshift systems.

No.
From what I heard they are noisy, and they shift at the worst time.
Have you actually seen on on the road? Didn't think so.

I thought auto transmissions were silly in cars, let alone bikes. Give me freedom! Then again, I'd prefer friction shifters to brifters.

What about a computer controlledt CVT though? Now that could be fun, you'd always be at the perfect cadence!!
The ones I've seen for the hybrids and at least one mazda are much smaller units than their discrete counter parts. It could work, right? Does anyone know what powers the the articulated parts of a CVT? My guess would be hydrallics, not sure how that would work on a bike.....

Shimano has an electric auto internally geared hub. I think the Bianchi Milano had a version with it (Nexus Auto D).

They're probably useful for very occasional riders who are unfamiliar with or clutzy with gears, but an internal hub that allows gear changes while stopped would probably be even better.
