So the Crockett piece I referred to originally wasn't a video but an article on his old SmartShooter (oxymoron?) site and the URL is dead. I have a copy of it saved as a PDF but it's probably far from appropriate or legal to provide it in total. But some of the better pieces of text:
He shows a 3D gamut map of sRGB and a Fuji PG 4500 and Epson 2200, the maps show lots of colors of both devices outside the sRGB gamut (meaning he doesn't understand how to read the map)!
In hindsight, Will got the piece far, far more accurately written with a far better message than Gary! He's a bit confused about the differences in sRGB and output color space gamut. But he's a color scientist in comparison to Gary's awful video.
Oh right, thanks for sharing this old stuff for reference.
There was indeed a consistent error based on the simple assumption that printing happened in sRGB - end of story.
His explanation checked out as long as you accepted his facts as true.
Glad it has been corrected by putting the content offline.
Now that Will Crocket realized the conceptual error, it's hard to understand why he would encourage Gary's views.
Maybe both think that they're helping photographers not run into colorspace troubles (which might be true with some labs? I know nothing about that) by recommending sRGB, and that technicalities used to convince them really don't matter as long as they're heard.
Most people making something happily forget that a lot of what we do today is 99.99% (just made that up) built on top of previous work.

Well...
