I remember advertisements for Bendix 2-speed Automatic hubs,
"No Pesky Cables!"

Shimano achieves that goal differently:

When did maximum complexity become a bike design goal?

I was worried that Shimano would take away their biggest advantage, the last for months battery. But they arrived at the perfect compromise.

Why do you say things like that? If design simplicity were the goal rather than operational simplicity, we would still be riding downtube shifters and riding 27 1/4" tires with Shrader valves.

But Frank, it avoids the necessity of having to learn such intricate
skills as shifting with those infernal manual down tube shifters :-)

A note here Eddy Merckz - reckoned by some as the greatest bicycle
racer of all times used down tube shifters.

Meh. Anyone riding STI could have beaten him.

Started with four speed derailleurs if I recall.

Au contraire.

Simplicity is my fixed gear + front caliper with tubulars.
I stopped thinking about the bike years ago. It just works
so I just ride.

The revolutionary no cables will come with a supercap or ultracap and an
energy scavenging charging mechanism on the derailleur itself. Imagine
an eddy current driven dynamo using the chain motion through the rear
derailleur to turn it. Like the Magnic lights.
https://www.magniclight.com/en/

It only has to store enough energy to make a few changes, and as you
pedal (even backwards if you like), it will charge for the next change.

Even a magnet one side and a coil the other side of the moving chain
might be enough. As the passage of the chain varies the permeance
between the magnet and coil, so the magnetic flux in the coil varies and
an AC power source is made.

If Eddy was a true believer in down tube shifters, surely his range of
bicycles sold today would reflect that?
