This is a very wrong-headed view. There are a variety of other outcomes. For example, we could develop fusion power and perfect generalized manufacturing (3d printing), and have a massive die-off where only the top 1% of wealth holders survive as they disconnect themselves from labor classes and enjoy a post-scarcity economy where they trade influence by creating and playing ever-more-indirect markets. Or they could just de facto enslave labor classes rather than letting them die off. There are plenty of outcomes other than "capitalism undermines itself." It's possible to have faith without being religious, and Marx is a great example.
