I am not sure just what Marx had in mind when he wrote that "philosophers have hitherto only interpreted the world in various ways; the point is to change it." Did he mean that philosophy could change the world, or that philosophers should turn to the higher priority of changing the world? If the former, then he presumably meant philosophy in a broad sense of the term, including analysis of the social order and ideas about why it should be changed, and how. In that broad sense, philosophy can play a role, indeed an essential role, in changing the world.

The internet is something created largely by public funding.

Remember that in any major nuclear war, the first strike destroys the country that attacks; it's been known for years. The first strike of a major power is very likely to cause what's called nuclear winter, leads to global famine for years and everything's basically gone. Some survivors straggling around. Could [Donald Trump] do it? Who knows.

People are interested in authentic long-term, socialist goals, which is not what is usually called socialism. They should be thinking through carefully how the projected society should work, but not in extensive detail because a lot of things just have to be learned by experiment and we don't know enough to plan societies in detail by any means. But, general guidelines could be worked out and many of the specific problems can be discussed. That should just be part of people's popular consciousness. That's how a transition to socialism could take place.

In fact, what were called the socialist countries in Eastern Europe were the most anti-socialist systems in the world. Workers had more rights in the United States and England than they had in Russia, and it was somehow still called socialism.
