Meh? First, demand isn't necessarily zero despite the author's assertion based on the exhaustive data survey of asking "a couple of other people". For instance, SpaceXAI was convincing all the banks who wanted to work on the SpaceX IP to purchase Grok.

Would I use it? No. Am I at all surprised that AWS is adding it to Bedrock? Also no.
