I was just reading a summary from a book published in 2016 that talks about this:

Chapter 2, “Why the Technological System Will Destroy Itself”, develops the author’s theory of “self-propagating systems”—systems that compete against each other for power without any regard for the long-term consequences, since any self-propagating systems that take the long-term into account will lose their competitive edge and be out-competed by self-propagating systems that do not. Kaczynski ultimately argues that since the technological system itself is a self-propagating system composed of self-propagating subsystems that competes for power in the short-term without regard for the long-term negative consequences, that the logical conclusion of the continued growth of the technological system is the complete destruction of the biosphere, wiping out all complex lifeforms.
