Very surprisingly it's never mentioned that car turbos have very similar requirements - spin at 10K+ RPM at 10000K+ for or tens of thousands of hours with little expected maintenance.
They are often made of superalloys, yet regular cars, down to econoboxes costing 20-30k or less have them, and are made by the millions.
If you figure a way for airplane to stop on a cloud in mid flight to wait for a tow vehicle I have a Nobel award for you in whatever field you want.
