Is this guy still relevant?

Slay your heroes. He did brilliant things defending bitcoin but lost his plot when his star lost its shine

Nope. He, like many others before him, let it all go to his head and is now enslaved by the thing he projects in order to get engagement...

I wrote a post about him a while back that basically gives my take: #191801

He produced great work, once upon a time.

But then he lost the plot and sold his soul. And doubled and tripled down on it.

So, my answer is: NO.
