No, because as the history of hardware scaling shows us, things that run on supercomputers today will run on smartphones tomorrow. Current models already run fairly well on beefy desktop systems. Eventually models the quality of ChatGPT 4 will be open sourced and running on commodity systems. Then what? There's no moat.
Do you remember the Facebook phone? Not many people do, because it was a failed project, and that was back when Android was way more open. Every couple of years, a tech company with billions has the brilliant idea: "Why don't we have a mobile platform that we control?", followed by failure. Amazon is the only qualified success in this area.
I agree that a slight twist on android doesn't make sense. A phone with a in integrated LLM with apps that are essentially prompts to the LLM might be different enough to gain market share.
