Cerebras and Groq both have their own novel chip designs. If they can scale and create a consumer friendly product that would be a great, but I believe their speeds are due to them having all of their chips networked together, in addition to design for LLM usage. AGI will likely happen at the data center level before we can get on-device performance equivalent to what we have access to today (affordably), but I would love to be wrong about that.
