Yes. We're well on our way.

These links all reference process in specific areas with little or no context otherwise. For example, pointing to grain production increases does not acknowledge the required dependence on chemical inputs, water use, or infrastructure to move grained from large growth areas to those who actually eat it. Pointing to cancer treatment, while hugely important to those battling cancer, says nothing of what will plague us if we ever succeed in eradicating cancer.

If you have links or explanation of how we could possibly get to a world with no illness or suffering I'd be very interested. I'm also not expecting anything as that first depends on somehow already knowing what we don't yet know, like what will kill people once we cure cancer.
