I don't really get the value proposition of groq as a user, the performance is really poor for the token price. Data centres on the other hand are becoming a commodity, and I don't see any reason a priori to invest in groq specifically for something like that.
Groq is considerably faster and better at inference, they have a totally superior product to Nvidia for inference based tasks, which will be the dominant concern in the future.
Plausibly, take all the Nvidia hype and multiply that by a factor and that's what 'Groq' could be worth.
And there is no real commodification - there's Nvidia, Cerebras, Groq ... not many otheres.
