Ah yes. The Precursor is real now, you can read more at https://precursor.dev. As a baseline it can function as a password/authentication token manager, but as another user mentioned we're adding messaging features now.

Another thing I'm working on is IRIS, a non-destructive method for inspecting silicon chips after mounting on a circuit board: https://arxiv.org/abs/2303.07406 It's part of a long yak-shaving arc to make the Precursor more accessible by migrating from an FPGA-based system to an ASIC.

He is still working on it, the precursor, they're just starting development of the messaging app that will run on that dev platform and eventually run on the betrusted final device.
