Halide Cofounder Sebastiaan de With Joined Apple’s Design Team in January:

When de With published his essay, it was as an idea for where Apple might go. Now that we’ve seen and been living with Liquid Glass, his essay works even better as a roadmap for the direction Liquid Glass should head.

I really hope De With was hired, not only for his talent, but for the work he did behind his essay: Physicality: the new age of UI.
