Nick Bostrom has his analogy about technologies being like lottery balls. Most of the time we draw "white" balls and technology has almost no downsides, sometimes we draw a "gray" ball and there are pros and cons. We've never drawn a "black" ball technology out of reality's bag of tricks because we wouldn't be here discussing it if we had, although he suggests things like AI or homebrewed viruses could be a black ball.

Drawing ball after ball has kept humanity progressing. Extend his analogy a little further. What if there are no more white balls to draw? What if we are "impeded" from drawing them by the fact that there are now more gray and black balls to draw instead of white? Or, since we have to reach further into this lottery jar, what if we don't reach them in time?

Malthus rested his conclusion on the assumption that we would never hack agriculture the way we have (nitrogen, phosphorus, etc). You rest your conclusion on the assumption that we will always successfully draw a new trick out of the hat, like find ways to recover all the rare earth metals from phones for which we have no current mechanism for economic recycling. You rest your worldview on the idea that our potential is limitless, that humanity's progress is inevitable, a god-given right if you will. I rest my worldview on the idea that nothing is guaranteed, that complexity begets fragility and diminishing returns, and that entropy will always, always, have the last laugh.
