I've done my own research. Not an expert by Dy will be a material of choice to keep permanent magnets (and missiles??) from overheating.

It's a bit like saying Lithium is dead cause one could use petrol, diesel or some new fandangled silicone or hydrogen energy. They can use those other things, but we all know that Lithium will take the majority of the energy storage / battery market going forward. Same thing for Dy. The mere fact that some such as Toyota are looking to try and get away from Dy should give people an inkling of where Toyota think Dy is heading!!. That is - a lot higher!!!!
