I love the book!

"The Congress" is to "The Futurological Congress" is to Stanislaw Lem like "Blade Runner" is to "Do Androids Dream of Electric Sheep" is to Philip K Dick. Both great movies loosely based on both great but very different books by great authors, each with something unique and deep and important to say, that all stand on their own and are worth knowing.

Wait until you've seen the Ijon Tichy miniseries. It's .. a different approach.

How long until humans have an actual "shelve" (indentation) on their pinkie at birth to rest their phone on?

a long time? You probably need at least 7-9 generations to select "strong pinky shelf" as desirable and I'm not sure any culture is yet?

I don't follow. You can grab leg and drag owner around. How's tail different?

A leg has rigidity due to its endoskeleton, as well as strong muscles with good leverage, which when conditions are right gives it insane strength as it can act as a mechanical lever. Since a tail does not have a rigid endoskeleton, it can not act well as a lever. It's functionally a rope attached to your butt. Like even if you go full kangaroo mode and make the tail more muscular than the legs, making the tail rigid…

But the lack of ridigity also means that it's actually quite hard to control someone through it.

If you grab someone's leg, especially near the foot/ankle, you are relying on the rigidity of the joints to be able to control their torso (and therefore their ability to fight back). The most disadvantageous position to be in is to have someone behind you, while they fully control your ankle/foot. Now you can't fully turn your body to face your opponent.

For a sufficiently flexible tail, that would not be the case. Some could be behind you and control your tail near the tip, and you could still fully turn into your attacker with your torso.

This isn't to say that a tail can't become a liability.

Never.

Actually, considering how low the birth rates in developed countries are, humans would probably (very slowly) become less and less suitable for modern life.
