I haven't been following estimates lately, but how much do people think it would cost in GPUs to approximate a human brain at this point given all the GPU performance leaps lately?

I had some recent discussions with Jacob Cannell about this, where he estimated that (with the right software which we don't yet have) you could build a human-level AGI with about 1000 modern GPUs. The amortized cost plus electricity (or if you rent from Amazon AWS) is roughly $0.1 per hour per GPU so the total would be around $100 per hour.

Schmidhuber's new NNAISENSE startup

FLI just gave Bas Steunebrink $196,650 to work on something called "experience-based AI" or EXPAI, and Bas is one of the co-founders of NNAISENSE. This EXPAI sounds like a traditional hand-coded AI, not ANN based. Possibly they set up the startup without any specific plans, but just in case they wanted to commercialize something?
