Old age and death is still the number one tool for solving: - empires and tyrants
- outdated societal opinions and prejudices (racism/sexism/etc)
- locked in privilege and wealth
- ossification of social roles
- stagnation within fields and industry ("Science progresses one funeral at a time")
We have no truly effective tools for these problems, except wait for people to die. I'd be much more supportive of ending aging if we had anything that worked.
