The result looks very interesting, and the blog post is well written (e.g., I did not know about the prior work re. Grover's algorithm and pendulum systems).
The blog post is also based on a recent FOCS paper, and the authors are reputable people in CS theory, if that convinces anyone to take a closer look.
It's like saying quantum teleportation [2] is BS, just because you don't like the SF sounding word "teleportation".

The "wormhole" thing was scientifically interesting as a quantum simulation of a non-trivial gravitational thing. A lot of the media stuff was garbage, but the actual science they did was quite cool.
