I found that the weakest part of the presentation. Kotlin and Ceylon both came out of corporate/industrial development. C#, JavaScript and Java continue to evolve entirely due to industrial funding. I agree that academia is not a great place to do PL research as all the other non-idea aspects of a successful PL don't get enough attention. But industry is doing OK at launching new languages. Perhaps he feels that's "incrementalism" but there's nothing wrong with making solid upgrades that aren't attempts at unicorn style magic cure-alls. It'd also help if we collectively got over our demand for our tools to always be open source. This has solid justifications behind it but it ensures that programming languages will always be spinoffs of other endeavours rather than having truly focused attention in their own right. When you take away the profit motive, you get stagnation, and that seems to be the main point of the presentation.
