I like differentiable programming a lot, but can anyone explain the motivation for Swift as their language of choice for this? I assume it was simply because they wanted to get Chris Lattner, and Swift was his baby. Julia seems like a much better target for this, I wish they had just dedicated some money or resources to that. I don't have a problem with Swift's language design per-se (although Julia's dynamic nature really lends itself more naturally to the sort of problems you might be trying to solve using differential programming, in my opinion) but its cross-platform support is terrible. Why would you choose Mac's boutique language as the foundation of your new paradigm?
