now that we have a cohesive look at workflow APIs, some issues remain:

createActivityHandle isnt really a handle, in the way that createWorkflowHandle and createChildWorkflowHandle are. it returns a function that you call.
- users are confused by the proxy destructure which a very fancy way of doing type safety and ensuring consistent naming
defineSignal/Query dont add much value since they just create an object
- extra setListener api that is doing the real work, basically 2 different functions branching by def.type

just taking another crack at api design.

Clubhouse is a great way to access celebrities but a terrible listening experience. They got all the growth factors right, but none of the retention and compounding factors.

Andrew Chen, Ryan Hoover, Michael Grinich and Sahil Lavingia think it could be a $100b company — and they have insider knowledge of metrics. I don't think Clubhouse is a zero - it has genuinely created a new category - it's just not very valuable. I'm taking the other side of that bet (but of course wish them well).
