I'm not advocating for it I just think it is impossible to have non biased news. It's even more impossible IMO to try filtering the news and find a non biased perspectives by finding commonalities and statistical averages between all biased news.

Whenever you think "Oh this news source isn't biased" it's because they have the same bias as you do. So we don't see it.

The example you gave about Galileo would require the "news sorting bot" to understand the science so thoroughly that it would be able to realize when a scientist is speaking the truth and being ridiculed by it. But at that point it would be AGI already and humans probably wouldn't be the ones doing the research anymore.
