You never know if people are going to love your pet project as much as you do. We had a hunch the community would appreciate Willow but like I said, you just never know.
My suspicion is Espressif (until now, hah) hasn't sold a lot of ESP Boxes. We were concerned that if Willow takes off they will sell out. That already appears to be happening.
Espressif has tremendous manufacturing capacity and we hope they will scale up ESP BOX production to meet demand now that (with Willow) it exists. The only gaiting item for them is probably the plastic enclosure and they should be able to figure out how to produce that en masse :).
I really hope so, I've been waiting for good audio assistant hardware forever. I hope this is finally the time where I ditch Alexa once and for all, thanks for releasing Willow!
