I would not be at all surprised. No speculation is too silly to have been seriously propounded by some philosopher or other, and lofty state gives no immunity to silliness.
[ETA: And of course, I'm talking about ideas that I've judged silly despite their being seriously propounded by (some) folks here on LessWrong that I think are really smart, and after reading a whole lot of their stuff before arriving at that conclusion. So one more smart person, however prestigious, isn't going to make a difference.]
But you changed it to "could be". Sure, could be, but that's like Descartes' speculations about a trickster demon faking all our sensations. It's unfalsifiable unless you deliberately put something into the speculation to let the denizens discover their true state, but at that point you're just writing speculative fiction.
But if this person is arguing that we probably are in a simulation, then no, I just tune that out.
So the bottom line of your reasoning is quite safe from any evidential threats?

This thread is for the discussion of Less Wrong topics that have not appeared in recent posts. If a discussion gets unwieldy, celebrate by turning it into a top-level post.
