Newer tech has added vast amounts of new functionality at the expense of making the older, simpler functions a bit more cumbersome and less reliable. Not everyone likes that trade off. For example, in the early 1980s, landline phones were indestructible, never dropped calls, and had 99.99999% uptime. VOIP phones are nowhere near that reliable, by any metric, but that's the price for fully redirect-able calls/messages among dozens of other useful features.
