Google produces other products than search - Android for example. Waymo is the best self-driving car company (but the problem is self-driving cars won't work for a long time, if ever).

The problem is all Google's products use the free-plus-advertising model and this has caused them to drift to serving the advertisers rather than serving the users. And that makes it hard to switch gears to offer more benefits to users.

The main problem is Google shifted from making search better for their users
