Additionally, cellular phones today do not have much longer range than cellular phones of 1991 (in fact most have less range, due to their lower transmission power and use of higher frequencies, as well as indirectly due to increasing crowding on most wireless frequencies). Cordless phones reliant on a land-line may exhibit somewhat longer range than they did in 1991, due to improvements in digital error correction and audio compression. Although the effective range of a single transmission at a given power and frequency would otherwise be reduced by interference from the proliferation of other wireless devices outside functional range and/or operating independently. Satellite phones also offer more terrestrial range than cellular or cordless landline phones, however their functional range has not greatly increased since 1991 either (being already sufficient to reach a satellite within line-of-sight above). A possible explanation for a perceived "longer range" is that cellular phone towers are much more omnipresent than in 1991, granting cellular devices much greater functional area even though their functional range from ''one'' tower is typically less than in 1991.

By most reasonable measures, the most important technologies on the list could be seen as the rise of mobile phones and the ability to easily share news stories (aside of course, from any perceived advent of high-powered laser weapons or televised robotic warfare). The first of these, mobile phone usage (and smartphones in particular) has led to a dramatic change in how people communicate, with a large amount of communication now remote, which was not as convenient in the 1990s (requiring, for example, setting up {{w|roaming}} at the carrier's office before taking the phone to another city) and impossible for most people a few decades prior: Low frequency wireless for personal communication was relatively uncommon in the early '90s and remains so today. Sharing of news stories person-to-person is partly blamed for the spread of {{w|fake news}}; misinformation has become more and more politically, legally and socially significant in the past few years. While wireless communication has certainly had enormous and wide-ranging effects, the factuality of the data communicated is arguably of greater importance than the means of its communication. The joke is that the impact of a technology on society isn't really about how exciting or dangerous it might look at first glance.
