I don’t ignore the “massive shift” to new tech because I know for a fact how much legacy hardware still exists. New tech changes, ISPs and telcos aren’t actually built on new tech, they add new tech, but there is a lot of 25 year old hardware around that only gets phased out when the people that know how to run it start retiring.
