That video is a fallacy. I see where Apple's marketing started now. As per everyone else back then, we wrote pretty much everything in Perl and occasionally C when Perl hit a bottleneck. GUIs were built in Tk, not in OpenLook. Still far easier and quicker than IB on XCode. TBH it took as long as it takes in Visual Studio now, which says exactly what little progress the world has made in the last 15 years.
