Do we still need fast lenses with great high ISO cameras?

Yes, if you’re serious about all aspects of photography. 

Fast aperture is not the same as high ISO. Aperture produces differing effects of depth of field that high ISO by itself does not. High ISO has differing effects on dynamic range and noise that aperture does not. A serious photographer wants both arrows in his or her quiver.
