See that slide that shows the bipartite graph of Problems on the left and Technology on the right. Typescript would be an extra edge in that graph and thus would impact the equation in the subsequent slides. So it would be a shiny new technology.
(I also think TypeScript is a great example of a category breaker here since it's a lot closer to a linter than a database. Sure, you have a new compiler stage so it's not quite free :-))
