High-Speed Rail in Europe

Here’s an article that predicts the completion of a number of high-speed railroad connections in Europe by the year 2045.  I don’t see it, because:

France’s TGV, initiated 40 years ago,  already offers services that extend to Belgium, Luxembourg, Germany, Switzerland, Italy, Spain and the Netherlands. Conventional TGV services operate up to 320 km/h (200 mph, and can hit as much as 350 mph).  Does anyone need to travel faster than that on a fairy small continent?

I’ve never been impressed by people who make predictions that extend 25 years into the future, projecting the completion of projects that aren’t even in the planning stages.  No specific technologies are agreed to.  HyperLoop?  MagLev?

In the words of Benjamin Braddock’s father in The Graduate, “This whole thing sounds pretty half-baked.”
