I can see the utility in this.

I have tens of thousands of photos, it’d be nice to search “[daughter’s name] holding blue teddy bear” and have it come back with the exact picture I have in mind but would struggle to find.

Is it worth the privacy and potential security issues, though? I’d say hell no.

I look forward to the future where we have powerful, energy efficient neural processing hardware, and a robust open source software ecosystem to do this in a more trustable way offline and on-device, or on a Nextcloud home server or something like that.
