He seems to go on describing the Stack Graph and the build/test/deploy/task primitives, the unified configuration between environments, build and test results caching, the platform agnosticism (even though we are heavy focused on kubernetes) and the fact that CI can be just a feature, not a product on itself.
One thing I definitely don't agree with is: "The total addressable market for this idea seems too small for me to see any major player with the technical know-how to implement and offer such a service in the next few years."
We just published the results from an independent survery we commissioned last week and one of the things that came out is: it doesn't matter the size of the company, the amount of hours teams spend mantaining this overly complex build systems, CI systems, Preview/Dev environments etc. is enormous and often is object of the biggest complaints across teams of Tech organizations.
So yeah, I agree with the complexity bit but I think the author is overly positive about the current state of the art, at least in the cloud native world.
