Turns out there’s not actually much functionality in these at all. An RFID reader and an RGB LED, whoop-de-shit.
Where did you get that idea? They have an RFID reader and LED, yes, but they also have a speaker, microphone, accelerometer, light and color sensor, near-field magnetic position detection, and then have to fit the battery alongside all of that, all in a 2x4 brick.
Here’s an example of what cutting-edge brick tech could look like.
That brick has a fixed option for what it displays without needing to be entirely reflashed, requires a 4x8 powered baseplate to operate, and compared to the smart brick, doesn’t have RFID, LEDs, sound, color, or light sensing capabilities, no accelerometer, and no ability to detect other bricks near it, along with having no internal battery.
The smart brick can play different (fully interchangeable without firmware reflashing) sounds based on nearby minifigures and interactable buttons and levers, can display lights and sounds based on rotation and movement, can change how it interacts based on nearby smart bricks, and can also be charged wirelessly and operate standalone. And of course, it’ll be able to respond to sounds later on too.
The brick from hackaday has a display. That’s it. It’s cool, yes, but it’s nowhere close to the smart brick.

It’s also not as SEO-gameable (since fediverse domains are inherently more fragmented than a large, high-reputation domain for SEO algorithms to rank highly), and doesn’t have an inherent monetization system (unlike platforms like Twitter with their ad payouts), so that’s a couple more things going for us.
