A neat toy for hobbyists, but most people can't justify carrying two devices. And as soon as you add phone functionality to it... you've just made a new (more awkward) smartphone.
My takeaway of their angle is: the companies making the apps and services that are used a lot often have incentives that aren’t aligned with their users. People want to see baby photos, Facebook wants to sell ads, people want to find information, Google wants to sell ads, people want to see what their friends are doing Instagram wants to sell ads. The “LAM” promises to wrap a lot of stuff under an interface.
The device itself is just the access point.
I like the angle. I don’t see it working with today’s quality of LLM understanding human intent nor with all of the siloed platforms.
