I’m sure you’re right, but the 32 to 64 migration was a little boring :)
Removing the CPU bottleneck offered so many new possibilities — including Apple *evangelising* at DRUPA!
Will they ever do that again?

Yes, it’s very annoying.
Even if you don’t switch profiles the use of the monitor space as a default makes retouching difficult unless the Finder and Dock are kept hidden from view.
We discussed this here in 2013 when wide gamut monitors met Adobe's new InDesign icon in the Dock and overwhelmed our retinas :(

It had a slightly different approach (more systematic, not so much imitating the “real world” as Photoshop (sic!) with pencils, erasers etc.), but was very powerful, and many people considered TIFFany superior to Photoshop.

When OS X appeared in 2001, TIFFany was one of the few heavyweight applications from NEXTSTEP that were ported to OS X / Cocoa. (Most NEXTSTEP developers had given up any hope of success and assumed Cocoa would lose against Carbon and die soon.)

Then, development of TIFFany suddenly stalled (an Intel version never appeared, let alone a 64 bit version). The reason was that Apple had hired the TIFFany developers to create what would become Core Image.

I like the story. The guy who wrote TIFFany also wrote the code for Aperture’s magnifier didn’t he? Great feature but, move it too fast across an image, it’s the guaranteed easiest way to kill Aperture.
But this story saddens me too.
There were so many possibilities back then. But, within a couple of years, it all got really boring. The consumer device became king and the Mac became transformed into a giant iPad with a locked down OS.
Your *bug* in a Mac is a *feature* in an iPhone.
