The problem I see is that it introduces another degree of separation between the user and the wider Internet. Instead of indexing sites, browsers are trying to interpret them for us. The extreme edge case of this is not having websites at all anymore, just apps and an omniscient AI that answers anything. Cool in theory, but in practice these omniscient beings really aren’t and instead are very fallible. Presumably these tools are also owned by corporations with shareholder values that are often contrary to user values. I can only speak for myself, but I experience these summaries as a loss of control over how I interact with the Internet and a step down a path I would rather not tread.

In this example the AI also does not provide anything valuable. It only defines a forum thread in terms of the question asked.
