Faster data rates, lower network congestion, more efficient spectrum allocation, and private commercial networks for IoT. There are many benefits. Although, perhaps marketing has oversold those benefits that will be passed into consumers. Largely, 5G will benefit network operators, carriers, and industry.

5G has not appreciably made “flying more unsafe.” If anything, this is a good push to start updating altimeters to spec (installing bandpass filters, better testing) which actually will make flying more safe because currently these altimeters are susceptible to out of band frequencies.
