Images, voice search and text search could be split up into different competing companies. Youtube is the second most popular search engine. That could be broken off of Alphabet. GMail could be it's own company. Google Photos could be it's own thing. Google Drive/docs/sheets could be it's own company. There's a lot of ways to break up google.
Gmail, Google Docs, Photos, Drive, etc. would all be rolled into a separate company. There would be no good reason to make Gmail or Photos separate companies. Photos would be a horrific business standing alone.
Why? Isn’t photo storage the thing most people care about for cloud storage?
Image recognition and organization is also pretty valuable to most people.
It’s only not a good business model now because Google makes all these services free. These services could make money on their own if they had too.
