There are a lot of opportunities to create great tools for designers – and you're right that QC has an uncertain future. However, QC is a really powerful tool, and shapes the way we design at Facebook. Whatever the future may bring, you can get real value out of this tool right now, and we think that's impactful.

Those lower-level patches can be integrated into your work in cool ways, they're there if you need them but don't get in the way.

A lot of individual parts of QC compositions can be replicated in the browser today, but the overall performance and rendering quality of QC for complex systems is still unmatched. As for universality, today most people designing for iOS and Android use Macs, so that's where we invest the most.

I hope you all give Origami a try :)
