Shortly after my recent piece about how generative A.I. search engine Perplexity is changing the web, the media and tech executive Geoff Isenman emailed me a poignant question on the minds of many web philosophers. Isenman wondered about the growing fear that increasingly sophisticated A.I. search will disincentivize digital content creators from publishing in the first place, and without that, he asked, “what will Perplexity summarize?” After all, Perplexity offers natural-language responses to queries instead of unfurling a list of relevant web pages. Will web consumers continue to visit sites and read articles when the information you’re looking for can be summarized in a tidy paragraph in mere seconds?
