The scope of Google's businesses never ceases to amaze me. I read that Google Chrome has 66% of the global browser market. That would be a huge business on its own. The browser fits perfectly into Google's model with their search platform as the default start page and all the Google browser apps like gmail, meet and maps visible in the top righthand corner.
They also have plans to create AI tools which can autonomously take over a web browser and perform tasks like research, booking a trip or online shopping. This is called project Jarvis and is set for a demo as soon as December.
