I ordered a rabbit r1. I can see it’s missing some key functionality (Bluetooth for headphones so everyone doesn’t have to hear?) But… I think it’s an example of a first, promising, step to the era of real voice assistants/agents.
This is a critical missing feature. I would never ever use this unless it's in my ear alone.
And I hope it doesn't become socially acceptable to be carrying these around forcing everyone else to listen to whatever this device has to tell the user. There is already far too many noise and inconsiderate people in this world.
Even gesture control would be a tough sell, and even that only if it's not "AR, where you push buttons projected across your field of vision" but "AR, where you can do the equivalent of gamepad buttons with hand movement anywhere the device can see the hand". Voice output (earbuds) would be far too slow for that kind of interaction, because you can't skim a list. Compared to the strictly sequential nature of audio, screens are the equivalent of embarrassingly parallel.
By the way, that slowness of voice output vs screen is also what I consider the true motivation companies had for creating those essentially free voice assistants: searching for product/service on a screen, even if it's just a small handheld screen, makes you pick from a list. With voice in the other hand, going through the list is so slow and cumbersome that the chances for just picking the first, "I'm feeling lucky", are much, much bigger. The value of placement (bought directly or bought indirectly, "this must be very relevant because we know how much they can spend on our other ad services") is just so much bigger with voice. Chances are people are less likely to listen to the second hit on voice than to go to the second page on screen.
