I tend to think that if technology solves the aging problem that in itself will solve a lot of other problems.  We would of course have to have a sustainable economy recycling and using only the energy of the sun (in its various forms) and we would of course have to be sure everyone is part of the package, not just the wealthy.  I tend to think we are making good progress if you look at the statistics around the world, but have a way to go.

We will never live forever -- just indefinitely.  That, I have to keep repeating, since it doesn't seem to sink in.

There is a more serious danger I might predict if death from aging were to stop.  We would still be exposed to accidents, and there is a set of personality traits that make one more likely to die accidentally -- the thrill of taking risks, criminality, immediate gratification, and so on.  These people would selectively die out more than those who are more conservative -- leading over a few thousand years to an extremely conservative, risk-averse population.  This does not sound good.
