Who are these experts? And have they ever accurately predicted the future, much less helped us prepare for it?
For instance, Theodore von Karman headed up a group that predicted drones, ICMBs, supersonic aircraft, and a good bit more. In 1945. When the most advanced planes in field were piston powered and prop driven.
Since then, developments like the Delphi technique and prediction markets have helped to make forecasts even more refined. A more on the point question might be whether forecasts are simply become self-fulfilling prophecies since they're relied on so heavily by strategic planners in government and industry.
