I was trying to do something with delegates in C# but couldn't remember what the various bits were called since it's been so long, so didn't have the magic words for Google to work. ChatGPT sorted me out with my vague question and one followup. Ultimately, I would like to see more about the other side. If generative AI can make blog spam, then I think it can recognise blog spam. How far are we from implementing a reliable filter of useless spam sites from search results? I don't expect Google has a monetary incentive for this, but maybe someone else does. But from my story above maybe "search" is a thing of the past and for functional queries, we will just talk to the gatekeeper. Reading the actual words written will only be for leisure.
