Is a point-to-point Internet just wishful thinking? If we all just get some good antennas [1], we could point our antennas at each other multiple times a day and exchange large quantities of data asynchronously (within a small geographic area). My old TV antenna used to rotate internally when you changed the channel to locate the signal, it's just servos spinning antennas. I think there's value in both network designs. Reading articles like these gives me a hunch that fiber will never be secure, ever again, so an Internet that doesn't run on fiber is one I look forward to.
