How is he less relevant than Elon Musk?

He co-founded linkedin a platform every one knows.

Elon Musk invented the Cybertruck and has a weird cult following through Tesla.

i mean Elon Musk called some of his kids this:

X Æ A-Xii Musk, Exa Dark Sideræl Musk and Techno Mechanicus Musk

What opinion should i give more value?

If you are going to include a speaker's child-naming prowess as a factor in assigning value to an opinion, you might as well just flip a coin, go with vibes, go with the one that matches your biases, or all three.

When I was a child my brother taught me to always consider the incentives, especially the monetary ones, of a speaker. 'Follow the money'. So, in this case neither Musk nor Hoffman would get much traction with me as both of them are incentivized to form a pro or con opinion of xAI.

>He co-founded linkedin

That alone should be justifiable cause for exile from society.
