Weight is a vector quantity
Ehh, you *can* define it that way, but it's often defined as a scalar quantity W=mg, were m and g are both scalars, and *always* used that way in common parlance (and scientific parlance rarely considers weight). Even the most anal physicist, if asked their weight, would only give it in vector notation if they were trying to make a point.
That said, one obvious concern in the other direction is that the encryption schemes which we are hoping to be resistant to quantum computing based attacks have had much less attention given to them (in part due to them simply being much younger), and thus we have less certainty that they are even classically good encryption. And we've had now multiple examples of supposedly quantum resistant algorithms being cracked by completely classical methods. See for example
Which is why no one is suggesting moving to a post-quantum algorithm alone. What Chrome is implementing is a hybrid key exchange, ML-KEM768+X25519 (the X25519 part is a standard elliptical curve cypher). Unless your implementation is absolutely terrible, you can't decrease security by layering on multiple encryption schemes, so even if ML-KEM is no more secure than ROT13, it still won't introduce any new vulnerability.
