I just asked Bard to summarize the flat earth stance and it wasn't subtle about calling it out.

An excerpt:

There is no scientific evidence to support the flat Earth stance. The arguments that flat Earthers use are not convincing, and they are all contradicted by the evidence. For example, ships disappear hull first over the horizon, which would not happen if the Earth were flat. Additionally, when astronauts go into space, they can see that the Earth is a sphere.

The flat Earth stance is a fringe belief that is not supported by the evidence. There is overwhelming evidence that the Earth is a sphere, and the arguments that flat Earthers use are not convincing.

So, maybe there's hope, still?

I asked the same about the anti vaccine stance and it gave a similar result.
