My take is the 2005 google does not and cannot exist again because it was born in an era where the underlying tech became so much more powerful. Any company that happened to invest creatively in tech during that era became unfathomably wealthy.
I joined google in 2022 (and have since left), even as a newcomer it was obvious that not only was the golden era over, but the era after the golden era was winding down too. The atmosphere wasn't "The reckless innovation is over but lets make the product as great as we can" - it was "Just don't break anything and squeeze out 1 or 2% improvements where possible"
