What'd you say to potential client who says "I type my queries in Perplexity, not in Google"

So, recently I was speaking to a potential client and explaining the importance of working on SEO for organic traffic to their community. They said, "I don't search on Google anymore. I simply use Perplexity and it works for me." My response was simple: 1. LLMs will still need authentic human experience powered content. 2. Google might get replaced by Perplexity. But they'll have to reference the links too. So SEO isn't going anywhere; and you will need to optimize your content anyways. What'd have been your response?
