Kaku's last book I've read and enjoyed was The Future of the Mind. However for the last ~5-7 years he often assumed what I call a toxic position in science: anything that's not canonical or "peer-approved" must be wrong, sometimes without even going into the disproving attempts. Then comes the unnecessary and really disgusting alarming when it comes to climate & AI. I respect him as a scientist, especially from a historic POV, but he dabbled to much into politics and popsci, and I for one was one of those people who looked at Kaku especially because he was not part of the cringy, popsci group.
