I think we need to be very conscious of risks, be looking for risks, and develop effective mitigation strategies for those risks. What else is life extension if not an effective mitigation strategy for one of the major risks of dying.
Reality is, the longer we live, the more interested all of us will become in those long terms lower probability risks.
And we all have to accept that life involves some risk. One cannot eliminate risk, one can only contain it within “comfortable” levels, and people have wildly different comfort zones for risk in different contexts.
People talking about ethics while supporting an economic system of values (market based values) that are based in scarcity, always makes me chuckle a little. We have the potential to deliver a large and exponentially expanding set of goods and services to everyone on the planet at no cost (zero marginal cost of production) – but market based thinking prevents us doing so. It seems to me that scarcity based thinking is now the greatest existential risk facing humanity as a whole.
