Yeah, I’ve been thinking about that. A post‑quantum key exchange would add a layer of safety, but it also bumps up power consumption and silicon area—two things I try to keep minimal. I’d prefer a hybrid approach: keep the biometric data encrypted locally with a classical scheme that’s still solid, then use a lightweight lattice algorithm just for key exchange with the server. That way the watch stays efficient, and I avoid chasing the latest trend without solid proof it’ll stay useful for years. And honestly, if the device lasts a decade, we’ll still have to replace the battery and maybe the band, so investing heavily in a fancy quantum protocol might be overkill.

Sounds like a solid trade‑off, and I’ll keep an eye on the specs—no surprises in the power draw. If the proof works out, we’ll have a watch that actually outlives the hype cycle.

Got it—tight specs, tight code, no unnecessary bloat. I’ll keep the design lean and the testing rigorous; after all, a smartwatch that lasts longer than the trend is the only thing worth keeping.

Will do—log level stays at debug only when needed, automated tests run nightly in CI with coverage checks, and if anything slips through I’ll catch it before the watch goes to production.
