Okay so circa 2011 it was powering some labs. Don't think there are many/any frontier labs in 2026 running ps3's, or at least no one has provided any evidence of that still..
Much later, I got to deploy 20,000 PS5 chips to mine ethereum. When PoS happened, we shut it all down. Now those boards (BC-250) are being sold on ebay for $200 and people are running AI on them.
