I still think it's a worthwhile effort especially for sites that have a product or service to offer. The key to think about here is intent - at least as it stands currently someone may ask a question to a AI chatbot or type it in Google and the answer to the question may satisfy what they are looking for - but people searching for a solution will likely need to dig more and visit the website to evaluate if that solution is worth exploring. AI overviews give a link to the site it came from - so users can still navigate from it to a website.
