It's unfair to compare LLMs to early or even late stage Google.
Early Google was a very simple keyword search engine. Entering a question would confuse the algorithm returning results that sometimes matched the lower value words in your question. It was slick for the time but would feel tedious today next to the simplified output from free and local tier LLMs.
The reason Google and the internet feels tedious today has less to do with Google's ads and more to do with the gamed page rank results, the mountain of ads you find on websites that have aggregated all of the content that used to be useful on the internet and the lowering of information quality over the years.
At the beginning Google search was all about returning the best result,but that's ruined partially because they put ads over search results and because others learned to tricked Google's algorithm.
Sometimes I have a question that would likely require multiple searches on Google.
But sometimes I just have a name or a broad subject and don’t want to have to formulate a question and wait for a long conversation style answer.
If I wanted the 8086 manual or something. It’d be extremely cumbersome to use a conversation to find it instead of typing “8086 manual pdf.”
There is significant overlap, but LLM and trad search have their own independent use cases.
I mean that if you are starting a company, as the young Google founders were back in the day, there is almost always more money in having a B2B model instead of a B2C model.
If you’re one of the biggest companies in the world, you can do whatever you want.
Though I’d bet that Microsoft makes more money off of their cut from 3rd party games sold on their platform than off of the sales of their first party titles alone.
They ran it for three or four years floundering and if I recall tried to sell to Excite for $1M but failed before they bought Adwords and it started to work for them.
I don’t think it is some universal truth, but it was the reality of the time that people wouldn’t pay for search so they pivoted into advertising.
Then they needed revenue.
Enjoy it til it lasts but there will be ads and AI search optimizations.
