I sure fucking hope so. We're also going to need high-temperature superconductors to replace current MRI machines, which are going to become stranded assets when required liquid helium supplies dry up, which they will if we keep squandering the stuff.

Today I leaned that helium is a non renewable resource typically found in natural gas deposits and is used for way more vital things than balloons.

Got it in one. It's also a pretty vital consumable in most every high-performance rocket; it's literally the only pressurant suitable for liquid hydrogen that isn't hydrogen itself.
