It’s Reboot Time for “Operating Systems”

I can't tell if this article is too deep for me or is conspiracy theory gibberish. What does Goldman Sachs and the 2008 crash have to do with operating systems and dynamic languages? How is "category theory" "explained" in a single paragraph?

Yeah I'm in over my head. He says basically:

1. We have too many programming languages

2. Goldman Sachs is developing some cities to do programming language research (ish?)

3. Jumps off the deep end into how MULTICS handles control flow vs context better, and UNIX isn't good enough due to a recession in the 70s?

Sorry, I'm just lost here apparently.
