When I was a teenager I wanted to learn how to drive manual. So when I bought a car, I bought a manual transmission. And I learned on it. I did have my Dad to teach me - I guess it would be tricker to learn if you don't have anyone you know who can drive one to teach you.
I plan to always buy manual transmission cars. I enjoy them more. To me it isn't about performance - it is about enjoying driving. I don't disagree that if speed is the goal, then modern automated manuals are much faster to shift. But speed isn't my goal, enjoyment is. And for anyone who claims that the extra hundredths of a second per shift is important to them when driving on a road, I think they are crazy.
