I admit to being a software rather than a hardware person, and being more high-level at that, so maybe there's a technological reason for it but: WHY can we not just take a whole buttload of Pi Zero W based devices (N-O-D-E nano server style) running a mesh network, plug them in all over Philadelphia, and solve [some of] the connectivity problems in low-income neighborhoods?
(This train of thought started with "Ooh Pi 400! Affordable computer!" but then thinking that's not the real issue.)
(when I was Director of E-Learning at a state-fundee Academy with 3,000 students in a relatively deprived area, we couldn't do this because it 'competed' with BT)
