Why do you discard the possibility that Tesla will save lives in the long term? You may say it is unlikely, but it is not like Musk did not deliver world scale breakthroughs.

Also, regarding the medicine, do you really believe we do not do "unethical" medical testings? I guess it depends on your ethical standards and how high they are :)

But let's get back to cost benefit trade off. COVID vaccines tests were rushed. So it is obviously sometimes worth it.

There is a risk in not taking a risk.
