HTML for markup and CSS for presentation: valid?

What's the current thinking on use of CSS to deliver content including
alt for CSS images? Can this become sufficient if screen reader
support becomes widespread?
This will then impact techniques for SC 1.1.1 and 1.3.1 too.
Also content of C22: Using CSS to control visual presentation of text.

Consider:

Clearly screen readers exposing CSS tables is problematic:

It became bad practice to use tags like FONT and   attributes like
color, border, etc. in HTML markup with the validator flagging
warnings  . Now we have CSS providing a method for alt text.

Thanks a lot,
