5G is clearly not necessary yet, but it's also nowhere near close to being widely deployed (that will happen over the next 3-5 years). AR, and pervasive computing in general, will eventually make 5G more than a novelty however. in any case, i personally doubt apple will add 5G in 2020, as they tend to be conservative on wireless tech (including wifi, bluetooth, etc.), waiting 1-2 years after the first rollouts by early adopters (like samsung), to make sure the kinks are worked out all around (equipment makers and carriers too). 2021 is probably more likely for the first 5G iphone, and 2022 will likely be the year you'll want to buy it.
