Meta priced the glasses near cost and will give Muse away free; the Reality Labs loss is the subsidy that pendant startups cannot match.

Muse asks before it spends your money. Camera-free glasses have no screen to ask on, so the approval has to land on another device.

Meta's avatar model draws 320 ms chunks that an agent's turn can hide. Driven by a live caller's voice, a chunk would put lips at least 340 ms late.

Meta's Private Processing was built to forget. Its design for AI glasses remembers: ciphertext on Meta's servers, the key on your device.

Meta's FDA filing puts its glasses hearing loop at 9.25 ms. In an open ear that delay is audible, and its costs belong to the frame, not firmware.

Qualcomm's claim of a 3B model at 45 tokens a second on the VR Glasses chip needs the puck's entire memory bus, by my arithmetic.

By my arithmetic, Meta's VR Glasses panels need up to 40 Gbps uncompressed, more than the Qualcomm chip's one DisplayPort 1.4 output carries.

My last day at Meta. Reflections on the journey, gratitude for the team, and anticipation for what's next.

After four years building VPS, I've decided to leave Meta. The reasoning, the emotions, and what comes next.

Half a year in - what I've learned about operating at Meta scale and building VPS from inception.

Bringing synthetic data practices from Magic Leap to Meta - what scales, what doesn't, and new opportunities.
