My guess is that many of you find the current xkcd quite relevant.
For me, it is not only relevant, but it makes me aware of changes outside of what I have been able to perceive.
To be specific, I have only had a smartphone for 13 months. Since the beginning, my realization was that the cellular data network was generally more reliable than WiFi. So what I have been doing was to use the cellular data network to get better performance, and to use the WiFi chiefly so that I’m not using up my data. It did not occur to me until this xkcd that once it has been the case that the WiFi was more reliable.
It is yet another reminder of how one extrapolates beyond one’s involvement with something, and the rapidity of change.
