Is The Thought Emporium real?

cross-post: https://lemmy.world/post/1426387

I stumbled upon this channel long time ago. Since then he claims to have Grown Real Spider Silk Using Yeast or taught rat neurons to play Doom.
The way he presents the content doesn't sound like a complete fantasy but my understanding of the topics is very rudimentary.

What do Lemmy biologists think about this channel?

And what do Lemmy scientists in general think?
