Why are you correct even though the early Marxists (who posited that capitalism would inevitably lead to socialism) were wrong? We have had mass production for a hundred years without any hint of socialism.
And I would like you to be right, by the way. But why should I believe you?
Doesn’t most of the developed world already have various forms of socialism? The U.S. is an outlier here, which is due a number of factors unique to this country.
We have state supported pension plans in most developed countries, unemplyment insurance, these large welfare states with extensive public education, national health and so on, so while the means of production mostly haven't been socialized, the fruits often have, through taxation. Now, some of this existed before the Industrial Revolution -- I wasn't aware how much until I read Karl Polanyi's The Great Transformation, which is a more important book now than ever, I humbly propose, but the scale is dwarfed by what we have now. And as Polanyi points out, we did get socialism as a response, as well as fascism, which was often btw called corporatism (as in the nation as a single body, not having to do with companies). Liberal democratic capitalism won out, for a while, and in large part because it became social democracy, or so goes a claim to which I subscribe. Without the social welfare aspects of modern democracy, the system would likely have broken politically.

You don't seem to know your history.
The US was on track to enact UBI. The US was socialist directly after the great depression.
Some of the most successful capitalist societies (the Nordic countries) have socialist elements.
