I touch type with my pinkies always on the control keys, not sure why you would have it any other way as a programmer. That might be suboptimal for typing text, but programming has so many special characters, and interacting with editors, browsers and such is usually better done with mouse and shortcut setup, so pinky on ctrl makes switching to mouse seamless.

And before you say I'd be faster with a typical home row setup, I program fast enough to compete with the best in the world in competitions, editor and keyboard enthusiasts talks a lot but they don't really deliver that extra speed in practice. They optimise for one use case and ignore the others, so they don't get faster overall.

I am not sure people really optimise for speed, they do it for comfort. When I moved to dvorak my speed dropped by quite a bit and I never regained it but that was done for comfort, and it is more comfortable no doubt.

    I lost the speed because I wasn't doing as much documentation as I used to with qwerty.   For development, that loss of speed hasn't made any difference because I type just as fast for development purposes.

    But my main point is the people I know have not optimised things for speed, they have done it for comfort.  A ten hour trip in a plane takes the same time in business class as it does in economy but one is a nicer way to travel.

   I wouldnt run out and tell everyone to change their setup, people are usually driven to it for one reason or another, either just curious or have an issue they need to address but on a topic of ergonomics, thats exactly what ergo keyboards are about.
