It's super cool but spoiler alert: just youtube aquaponics, it's not new (thank's reddit). People have been doing it even commercially for over a decade. That said I think what he says about future generations learning and getting excited about farming techniques is important and it's a really awesome concept.

I'd be lying if I said that I didn't think about building one of these after first learning about it! Also thinking how to maximize produce per/sqft/unit etc..

I think access to cheap, small and powerful computers would probably improve and it make it turnkey. My guess is it is pretty complicated to get all the factors right. Figuring out things like why are my fish dying, why is there a disease in my lettuce, etc., can get complicated.

I think the really interesting bit was the suite of sensors with automated alerts that get sent out that he was experimenting with.

In theory it could allow for this to work at very large scales with very little staffing, which seems counter-intuitive given the complexity of the setup.

Extended out a bit, and most of the very common problems could even have automated solutions (increase water, adjust ph, cycle on-off grow lamps, etc.)
