One thing I find interesting is that people still react to Google being down, half-way down. ChatGPT was down yesterday, almost no one cared.

Google being down means gmail, youtube, google docs etc are down in addition to search. Other services that depend on google's services are also down. It affects many more parts of workflows or entertainment or whatever.

single point of failure

ChatGPT typically has two nines of availability, it's down regularly.

because llms are a commodity, but good enough actual search isn't?

That's not entirely true. They provide (partial) search for both Ecosia and Kagi and both of those to have excellent search results. Google can provide good search, they just don't use it themselves.
