No psychopath would.

I am a physicist. String theory already unified QFT and GR and that doesn’t mean it’s a verified physical theory, you need to validate it through experiment. It’s physics 101. Just watch some Sabine H. videos to see how she speaks about string theory being a failure besides being mathematically consistent.

Although the theory is promising, the duo point out that they have not yet completed its proof

Physics is not math, you can’t “prove” a physical theory. You make predictions and through experiment or observation Nature has the last word.
