That’s right. Seems 
's current culture war fixations have made him sufficiently less interested in his older bullshit promises.
He will grift on, but seems he’s losing interested in the space grift. He’s posting cringe Gambo “AI” videos showing Gambo’s favorite objectified SV victim and mistreated actress being a DJ at a Gambo-setting dance party instead (not linking that shit, look for it if you dare).
The light of consciousness may not extend to the stars within his lifetime by his own admission, which means if it ever does it won’t include his dim smoldering light nor will it be his bigoted and emotionally poisonous consciousness. 
I didn’t like the way The Dark Forest, the second Three Body Problem book, portrayed this. ”Of course there’s no intelligent life out there, because they’ll just be destroyed by a more advanced civilization once they find out, because everyone is always hostile to each other. This also extends to the last remnants of humanity in space killing each other.”
I argue that in many cases (not all, but hear me out), it’s an after-the-fact justification for the difficulty in coming up with alien life that feels sufficiently “alien” to not feel like a Star Trek makeup job.
To be fair to the TBP trilogy…

Some civilizations have been fighting an endless transdimensional grudgematch to the point that successive inevitable dimensional collapses purge all the races that aren’t hyper survivalist and also hyper advanced. The trisolarans are an example of a primitive civilization who’s experiences have somewhat mirrored this extremely poisoned outlook.
