There have been scientific breakthroughs throughout human history and none of them "liberated" humanity in regards to sickness, poverty, energy, travel, entertainment. Why should this one now be different? There will always be sickness and poverty in a capitalist system that is built on the exploitation of others to sustain itself. During capitalism, medical ånd technological advances such breakthroughs might bring will always disproportionately benefit the rich. Sickness, poverty at least could already be "solved problems", as some people I think say, if not for class injustice in a system that depends on inequality to function.
