I think this is cool, plausible and warrants investigation, but not suspension of disbelief. There needs to be a better way to go about this than responding "what about Galileo!?" to any principled application of critical thinking.
One has to set prejudice to the side and examine the claim being made to apply criticl thinking.
These are big scientific claims, but the work is clearly too premature to make those conclusions, and it lacks the connection to prior work and peer review needed for making priority claims. It's really great hacker-tinkering work though, and it could turn into solid science if they take more care with it.
If this effect is real and truly novel, my cynical expectation is that someone already established in focused ultrasound will read this, apply a more rigorous approach, and get the recognition that they are hoping for through more establish channels.
To be frank the reason that make me question it the most is how repetitive the redaction is. Seems LLM-like.
However, that's not a valid reason to discard an interesting result.
This reminds me a bit of the escherian staircase video from 10+ years that went viral. A bunch of college students walking down the stairs, acting amazed when they found themselves back at the top. It was great acting and video editing, but it was fake and all part of, if I recall correctly, an art project.
I don't want to dismiss it outright either, seems cool as hell. But it's remarkable to me that all it takes is a blogpost to get this amount of uncritical acceptance of a demonstration.
