Not sure they will do that. Really hard to guess what the future is for ChromeOS. I don't know that developing it into a good general purpose OS is their aim.

ChromeOS seems like a very strategic product niche for Google. Their big business is advertising and the Chrome browser and Android seem like an insurance policy to protect that business.

ChromeBooks focussed on the education market almost to the exclusion of all else and their main selling point there was cost. Now with a lot of low quality, low margin hardware dead or running out of software updates they risk being viewed as the single use plastics of the computing industry. I am sure that influenced the pairing with Framework but it might be too little too late. It still doesn't address the software update situation. The Android model of manufacturers dropping support the moment they have our cash isn't sustainable. I wouldn't be surprised if eventually consumer legislation catches up with it in some markets.

It is hard to see how the ChromeOS experiment benefited Google's core business. I am sure they made millions on education cloud services but it is pocket money compared to Google's main source of revenue. Without knowing exactly what their thinking was going into that market or what they achieved I don't know how much priority they are likely to give to turning ChromeOS into a compelling platform for the general population.

Chromebooks found their way into enterprise niches and were gifted as zero support browsing appliances for grandparents but the push into those markets never felt focussed or important to Google. I doubt Google execs think about ChromeOS the way we are thinking about it.
