"showed this to my son - coming up to 15 - and his reaction was "what a piece of shit. No kids will use that. Give them something they can actually use to make something - like a Raspberry Pi"
This device is not aimed at him. This will be aimed at 13 year olds and the idea will be to spark an interest and demonstrate that these things are doable, then they might go looking for a Raspberry Pi as their interest expands. If your son has already done some making with a Raspberry Pi then he is well past the target students for this device.
Remember the Recorder music lessons in primary school? No kid wants to grow up to be a recorder player, they want an electric guitar. But the recorder was the simple cheap instrument that was used to find the kids with the aptitude and inclination.
