The hardest decision a company, especially in tech, can make is to disrupt an immensely successul business of their own before their competitors can. Apple killed their biggest cash cow, the iPod, to push a smartphone. Netflix killed its entire business of DVD rentals in favor of streaming. Microsoft stopped selling software in boxes and pivoted to SaaS. Similar to all of these the business of typing words in a search box and getting 10 blue links was dead the moment ChatGPT got popular.
