We are not going to return to capitalism as we know but the same goes to socialism as well.
There is not any viable system that could be the one or the other.
It will be a mixture of the two in order to keep a balance in metrics that cannot be improved in capitalism or in socialism itself.
Socialism and capitalism were invented by people. These are far from ideal social systems. At the same time, everything moves and develops. We really will not return to the society in which we lived earlier. Now the edges of capitalism and socialism are being erased, we are moving towards the creation of a society that is not in the textbooks. Perhaps we do not need any political superstructure. We will simply develop, observing universal human values.
