It’s even happening implicitly now when chat crawls some vendors site and proclaims their solutions as the answer to your question
After 5-7 minutes of work, it returns many results, yet it's citing 2 specific websites as sources, one of which was blogspam you'd write to get visibility on Google results.
So I guess we're heading towards a future where websites will be optimized to increase the probability of chatGPT and AI tools to use you as a reference and link to you with confidence, regardless of their sources.
I wish for it to only use sources that are older than 2019 and have zero ads and referral links, haha.
