Yahoo was the go to for search engine.
Hotmail was the go to for email.
People will just go to where it will benefit them more.
Google search results are rubbish.
The only thing i still faithfully use them for is its reviews, gmail, map and youtube.
Google has already diversified but their revenue still largely depends on their ads, iirc 80%.
They can't fight back with an Google AI search which gives you the answer right away instead of showing advertisers link on top
Most people are willing to pay for their search engine results, not youtube/android or whatever.
Youtube is likely expensive to run.
Google may not die, but they are definitely affected in a negative way.
They have resorted to dirty tricks to squeeze more ad revenue from their advertisers and I've long assigned my budget to social media which sees better results
Even their AI released to the public does not meet up to the expectation, and you can tell how reluctant they are in allowing this realm to grow.
I really don't see how they can get out of it unscratched .
