Agreed! This stood out:

> The laws of physics definitely allow for functional subluminal warp drives

“Definitely”? That feels like an exceedingly bold claim, given the nature of the thing we’re talking about. I don’t believe we know enough about “functional” machines comprised of multiple Jupiter-masses of exotic-if-not-quite-fictional matter to start using words like “definitely”.

It's also a very bold claim because a warp drive will violate Newton's Laws. ("Technically we're moving space, not the ship itself," you might say, but Nature usually ignores semantic arguments.)
