Simple hypothesis. Top 5percent of US wealth now belongs to top 50 richest American. Even if you ignore corruption, lobbying and any ill intent you can definitely conclude that this top 50 individuals have better way of getting return from money than rest of the population. Even if if their delta of return is 5% we can assume that withing next 50 years there is a high probability that these guys will own 30-50% of wealth. I have a strong belive AI will acclerate that further.
A major advantage Google has is youtube. Most of the content in web for Indian/Asian language is present inside youtube videos. If that content can be transcribed with decent precision youtube can be huge content booster for such language models.
This is an extremely important point. Something like ChatGPT without attribution can completely kill the open web. Every company will keep their information in closed walled garden if no traffic is flowing through them . I don't see a scenario where something like stackoverflow can exist if no one goes to the site.
