Mostly I would say that things have improved quite a bit since 2012, but only places that either had pretty bad dial-up or no service at all should be looking at changing right now. However, the new stuff coming on line is coming on line very fast, launch costs are dropping, and so it's probably worth marking the calendar and checking now and then, annually or so -- IF you are located in a hard to serve area. If you need a high speed internet connection on an offshshore drilling rig, a very remote weather station, etc., things are getting more reasonable.
As for whether direct satellite internet will ever be able to directly compete with cable/DSL/fiber in their "home zones" -- I would not want to bet it could, but in this field, five years is forever, and "impossible" tends to be temporary. So a few minutes a year spent checking to see what has changed could be very worth your while.
