Sure, I learned on stick-shift and drove several years with a variety of cars and trucks, including 3-on-the-tree 1978 Suburban (manual steering, manual brakes, what a bear that was!)... never drove a double-clutch though.
Manuals - while they absolutely can be a fun riot - are losing their advantages over automatics, including fast-locking TCs and DCTs and such.
Car manufacturers have to certify each car type - if they offer an automatic and a manual, that's two different cars to the US government's eyes, and both have to be tested.
Plus, of all the major auto racing circuits, only NASCAR still uses stick shifts. That ought to tell people something...
