Sharpening

My perception is that as each generation of sensor has had
higher and higher pixel density, the need for sharpening has been
reduced.

By this I mean that sharpening is basically a means of smoothing
over transitions among the pixels and as they have gotten closer
together the non sharpened or lightly sharpened appearance has
improved.

I don't mean to imply that learning good sharpening procedures
is not important to becoming a better photographer, but rather that
as the pixel density goes up it becomes relatively less critical.

Kind of thinking out loud, am I on the right track here ?

This is pretty much as close as you could come to the opposite of sharpening in the number of words you used. Sharpening is all about making transitions more perspicuous.

Quite the contrary really.

As each generation brings more and more pixels,
pictures are being downsized further from the original than ever before.
Post resize sharpening is a more common practice now than it ever was.

Re: Sharpening

Sharpening is not as related to the pixel density as it is the strength of the Anti-Aliasing filter. Sharpening is a process of compensating for the filter's negative influence on perceived sharpness. Additional sharpening is done for different output or crop operations.
