My favourite "wacky theory" is that Einstein general relativity can be derived from quantum computing, https://arxiv.org/abs/quant-ph/0501135.

In general, I love such novel concepts (rather than slight refinements of existing). They are like seeds - the vast majority of them won't sprout, but one in a thousand (or million) will change a field.

The same way as one erroneous paper on superluminal communication got refuted by the non-cloning theorem - which gave raise to quantum cryptography and quantum information in general. I recommend reading the backstory in "How the Hippies Saved Physics" (https://en.wikipedia.org/wiki/How_the_Hippies_Saved_Physics).
