Everything you’ve been told about EV battery failures is wrong (there's a major complexity problem)

A viewer asked me recently an innocent, and seemingly simple, question: Why are EV fires in the news all the time, and yet power tool batteries (which use the same fundamental tech) are so ubiquitous and seemingly safe? The answer opens a wormhole into the non-linearity of complex systems and failure mechanisms. Prepare to bleed from the ears.
