Kind of. Due to the (near) linear response of sensors, as opposed to the decidedly non-linear response of film, there are some technical differences between how digital and film work underneath in terms of optimal data representation.

Very true. When I switched from film to digital, there was definitely an "exposure learning curve". Where I was use to the substantial shoulder of Fuji cromes (loved the old RMS, less so Provia), I'd routinely overexpose a half to whole stop from my incident meter. Suddenly, with digital, I'm now shooting almost on the meter. It took me a shoot to realize, "We're not in Kansas anymore, Toto". It was good thing I shot RAW and not JPEG, because most of the blown highlights held. But, there were a few sweaty palms when I first opened images.

What happens when the scene exceeds your dynamic range? Your camera, left to it's own devices, will probably give you an average losing detail at both ends.

Bingo. I'm used to quickly flipping my 5D over to manual to get shots that aren't possible letting the camera handle things:

This sunset is two exposures combined into a final image. I made one exposure for the majority of the scene, and another separate exposure for the sun, which is about 5 Ev away from the rest of the scene. That's not something you can just do on Aperture Priority and spinning the back dial to lose 2 Ev in compensation.

Thing is, I've gotten all of the buttons and dials on the camera memorized now. Didn't even have to look what I was doing -- just counted clicks and fired away.

Very nice! And here's one where I preferred to let some highlights get blown (you can easily see where) to retain shadow detail that was more important ...

The blown out areas are hardly noticeable in this (excellent) shot. I think it works very nicely. What I hate are images where the subject of the image is a sky with big white blown out blobs of cloud. Or people's faces where half the subject's nose and forhead has been blown past 255. Yuck.

This is pretty ridiculous. Let's just automate everything so we don't have to do that painful thing some refer to as "thinking".
Why not just completely automate pianos and guitars and paint brushes. We can program them so we can just type in our feelings, and then the piano pumps out a catchy tune and the paint brush? What's next? How about a machine that automatically knows what we're thinking/feeling so it can tell the other machines what to do for us.
We've got the manual, we've got the auto. Creativity comes from the freedom to choose and make our own decisions.
