Pro stuff gives a glimpse of if we lived in a perfect world, SDI (and HD-SDI) would have been the de facto standard for video everywhere.
I then came to love the simplicity and reliability of SDI. Nowadays I work in uncompressed ST2110, and while there are many advantages of network based video and audio, paying $1,000 for a QSFP to handle just a few streams is a hard pill to swallow!
