Well, if the solution is vaccine-based, no because it *does* train the immune system, and often in better ways than virus exposition. But if the solution is air purifiers everywhere I'd be inclined to agree, the same way as kids growing up in perfectly clean room and never going outdoors often have allergies. On the other hand, having access to clean water may have made us more susceptible to catching the shits when going in third world countries, but I'd take our clean water system and sewers over those of India any day. Dying of dysentery is no fun. Neither is dying of Covid. So maybe I'll let professionals debate this one (and not investors).
