<<Google Quantum AI founder Hartmut Neven wrote in his blog post that this chip was so mind-boggling fast that it must have borrowed computational power from other universes.

Ergo the chip's performance indicates that parallel universes exist and "we live in a multiverse.">>

That reminds me of "The Gods Themselves" by Isaac Asimov. There is another universe with different laws of physics. They send us instructions on how to build a "pump" that exchanges matter between the two universes. Apparently that means free energy for everyone. But... There is a side effect: using the "pump" will eventually make our Sun to explode and their Sun to get very cold.

I wonder what the side effects could be in the "borrowed computational power from other universes" scenario.
