      A great read. My own obscene note would be nature ain't classical, these classical conjectures are all "unnatural", the quantum versions should be the focus ;)https://twitter.com/rrwilliams/status/963472189977743371 …

      For the Springer LNCS 10,000 volume, I wrote down a few thoughts on various open problems in complexity theory (trigger warning: some folks may find some of my answers surprising/heretical/obscene) http://people.csail.mit.edu/rrw/likelihoods.pdf …

      Thanks! Yes, I kept the discussion focused on stuff I know more about... :)

      I don't think anyone knows much about "quantum circuit lower bounds." Am I wrong?

      I think you are right (which is a great reason to work on it!) There are some interesting oddnesses: see for example one of @michael_nielsen s last papers before leaving quantum https://arxiv.org/abs/quant-ph/0502070 …

      You may have meant a later followup, e.g.: https://arxiv.org/abs/quant-ph/0701004 … (Thanks Dave. I regret not developing this much further. Though Lenny Susskind & co have been: https://arxiv.org/abs/1608.02612  )

      I have always had a suspicion that you are still secretly working on this in an attic somewhere. Suspicion. Or a dream. Or a nightmare.

      It certainly seemed - and seems - to me a much more natural problem than classical circuit lower bounds. But that's not to say easy...
