Why 'more or less stopped using ISO'?

In a recent thread where the OP was about base ISO
What determines a sensors Base ISO?

I was unclear about the following posts ...

Bob, even with film ISO rating is not very useful, it is just some approximate guideline. It is even less useful with digital. You know that...

I do know that, Iliah. Personally, I've more or less stopped using ISO.

I'm in the category of "not knowing that" ... about digital ISO being less than not very useful. Please clarify.

  • Is this specifically about "iso-less sensors" like many Sony and Nikon cameras?
  • So for such cameras ... just leave ISO at the camera's base ISO (typically 100)?
  • ...
  • Or does this also applies to Canon DSLR's (which I don't think can be described as iso-less)
  • Or because modern DSLR's have so little noise that use of Auto-ISO is appropriate?
  • So bobn2 and Iliah aren't concerned about what ISO is picked by Auto-ISO?
