So what are the main differences nowadays between them for the driver?
I think technically the 'zf auto' is a manumatic and not a semi automatic.
And a dual clutch gearbox or a SMG is a semi automatic:

I think in the end the biggest difference is whether you let a computer choose the gear (automatic) or that you do it yourself (semi-automatic, manumatic or manual).
Because the thing a computer can't do is anticipated driving. For that the human mind is by far superior (if you know how to drive and understand vehicle dynamics of course).
computers get smarter and smarter, for instance use GPS map data to predict if a corner is coming up, but they can't anticipate on where you want to go or, most of the time, what happens on the road (obstacles, traffic lights etc), that still dictate on what gear one should choose.

Thats basically an SMG I think?
Note that this is not similar to the mondial valeo clutch. Thats an automated clutch afaik.
