The original quote from Yvain was

I suppose the difference is whether you're doing the Intel attack now, or in a hypothetical future in which Intel is making brain simulators that seem likely to become AGI. As someone else mentioned, if we're talking about literally THEY ARE BUILDING SKYNET RIGHT NOW, then violence seems like the right idea."

Emphasis mine. In this original quote, in the hypothetical future, where Intel is building brain simulations that seem likely to become artificial general intelligence, he supports violence. As clear as it can be.

His subsequent re-formulation to make himself look less bad was:

Even Yvain supports violence of AI seems imminent". No, I might support violence if an obviously hostile unstoppable SKYNET-style AI seemed clearly imminent

Now, the caveat here is that he would use brain simulators built in the hypothetical future by Intel to be an example of "an obviously hostile unstoppable SKYNET-style AI" , a clear contradiction (if it was so obvious Intel wouldn't be making those brain emulations)
