Will helium be gone in 15-20 years?

Excuse me, I couldn't help but notice your mention of helium's potential disappearance in the next 15 to 20 years. Could you elaborate on your concerns? Are you referring to the depletion of helium reserves, or is there another aspect to this prediction that I'm not aware of? Also, what impact would such a scenario have on various industries that rely heavily on helium, like medical imaging, space exploration, and electronics manufacturing? I'm genuinely curious to understand your perspective and the potential implications of this prediction.
