How do you imagine this might be productized/useful to more people? I was not aware of this relationship and it seems like an important primitive, but it’s not immediately obvious to me what could be built. Do you already have ideas?
Concrete example:
Your npub: npub1kuy0wwf0tzzqvgfv8zpw0vaupkds3430jhapwrgfjyn7ecnhpe0qj9kdj8
Your testnet address: tb1pkuy0wwf0tzzqvgfv8zpw0vaupkds3430jhapwrgfjyn7ecnhpe0qxdufq2
Notice they are almost identical characters.
So I just sent you 1 million testnet sats here:

I just used a directive in my subkey (see below) to send you the sats. So much is possible!

Discussion
I believe the future is synthetic. So machines working together. And humans too, when they are ready. The main advantages I see is global state, infinite memory and orchestration.
