Even the battery comparison is generous because improvements in battery tech actually have made it out of the lab and into consumer products. Further, a lab battery actually functions as a battery, whereas a cure for fake mouse Alzheimer’s is several steps away from being proven as a cure for human Alzheimer’s. Alzheimer’s research is more like research into room temperature superconductors. No one has proven that what they’re seeking is even possible, but it sure would be nice.
