I can't watch the video until I get home, but my first thought on seeing 100/2 was WANT!
Thinking about it though, it actually has less light collecting ability than an 85/1.4, so even considering things like sensor resolution and MTF, I expect that with modern sensors, and being able to use a stop faster shutter speed at the same ISO, in the real world, I'd probably get better results cropping down a photo taken with the 85.
Plus there's the advantage of having some slop in the frame in case things move, and the middle of the frame being sharper.

Here's a YouTube video that's worth your time. It's a review of the
very old and very rare Takumar 100mm f/2.0 from around 1964.
