Is Michael Levin's bioelectricity work legit or pseudoscience?

>In a 2017 publication, his team cut flatworms into small fragments and dipped them briefly in a chemical that blocks intercellular ionic currents. Some worms regenerated into two-headed animals. The fleeting exposure made a permanent change; the animals consistently produced double-headed offspring across generations. Even worms that seemed unaffected—with normal shapes, gene expression, tissues, and stem cell distribution—recalled that quick dip. When cut again, these worms generated two-headed offspring. The experiments suggest that the pattern to make a two-headed worm isn’t stored in cells or genes, but in body-wide electrical circuits.
>“Electrical tissue memories could be storing all kinds of records of physiological experiences that could show up in future situations,” Levin says. “This is the first time where we actually show what this memory looks like.”
>Other researchers remain polarized in their views of these data, in part because it’s still unclear how a temporary tweak to electric signals might affect offspring several generations down the line. Many researchers remain skeptical, including Carrie Adler, who studies planarian regeneration at Cornell University. She says that our current understanding of how currents are transmitted between cells “doesn’t explain the finding that a brief perturbation makes a lasting change.”
>But on the other hand, even inhibiting chemical signals for brief windows of time can cause long-lasting changes in tissue healing, says Anna Huttenlocher of the University of Wisconsin-Madison. “So it’s convincing that there are key moments where if you alter bioelectric signaling, you can see a long term effect on regeneration or development because some key switch has occurred,” she says.
Sound a bit like Lemarkism.

But then again, he's still getting remarkable results in his lab, and has a path forward, while these critics not only haven't made any substantial progress in regenerative therapies, but seem unlikely to do so in the near future.
