I wouldn't bet on that.
Me neather, short term. But in the long run Capitalism will not want humans, we're too expensive. It also really makes no sense to work, I think this will become increasingly more evident. Note: Marx wouldn't agree with me. He would say that the rich will still have the means of production (automation), so the poor will still do stupid jobs to get paid that little to afford the products made by automation. It's basic…
"This “alienation” (to use a term which will be comprehensible to the philosophers) can, of course, only be abolished given two practical premises. For it to become an “intolerable” power, i.e. a power against which men make a revolution, it must necessarily have rendered the great mass of humanity “propertyless,” and produced, at the same time, the contradiction of an existing world of wealth and culture, both of which conditions presuppose a great increase in productive power, a high degree of its development. And, on the other hand, this development of productive forces (which itself implies the actual empirical existence of men in their world-historical, instead of local, being) is an absolutely necessary practical premise because without it want is merely made general, and with destitution the struggle for necessities and all the old filthy business would necessarily be reproduced; and furthermore, because only with this universal development of productive forces is a universal intercourse between men established, which produces in all nations simultaneously the phenomenon of the “propertyless” mass (universal competition), makes each nation dependent on the revolutions of the others, and finally has put world-historical, empirically universal individuals in place of local ones. Without this, (1) communism could only exist as a local event; (2) the forces of intercourse themselves could not have developed as universal, hence intolerable powers: they would have remained home-bred conditions surrounded by superstition; and (3) each extension of intercourse would abolish local communism."
Basically his assumption was that it will never be possible or politically tenable under capitalism to change the system to channel enough capital back to the general population (e.g. lets say via taxes to fund basic income to a level equivalent to lost incomes) to allow people to continue to consume enough to allow manufacturers to continue to grow, and that the result would be ever greater cycles of economic crashes until the contradiction of capacity to create wealth coupled with unemployment and/or underpayment gets great enough to cause people to rise up against it.
