It will happen in time. Like everything in aviation it's about dumbing things down and saving costs wherever possible. Gradually you will see ILSs coming offline, then pressure from airlines to drop the minima as there is no evidence of an increased risk to operations and the diversions are hitting the bottom line.
Then there will be a big prang somewhere and some expert will come out and say that the minima should never have been lowered. Committees will be setup to investigate this issue as a matter of urgency. They will report in a few years (delayed by beaurecrats under pressure from directors of airlines) by which time the status quo prevails and we carry on. Another report will come out muddying the water and disproving the first. The only solution will be to carry on with the status quo until someone very expensive can come up with a final report.
At the same time there will be pressures to ditch the expensive guy in the left seat and run the flight from the ground using "superbly" trained aircraft controllers who are highly proficient at MS Flight Sim.
