I changed the title because most people have never heard of David Gelernter.

He's a professor of CS at Yale (emeritus, I guess?) who created the Linda programming language and came up with the concept of "Life Streams," a forerunner to temporal feed-based social media, like Twitter and Instagram: http://cs-www.cs.yale.edu/homes/freeman/lifestreams.html

He's also arguably something of a patent troll: https://yaledailynews.com/articles/yale-prof-loses-625-5m-ap...

And he was also famously attacked by Ted Kaczynski, presumably because Kaczynski anticipated the significance of Gelernter's ideas (that, or the old Harvard-Yale rivalry got a little too heated).
