The article basically seems to be relying on some philosophy and muddy and different definitions in different contexts (philosophy vs science vs standard usage) of words like "fact". Then it talks about how things are getting more complex and we're spending more effort to learn things now than we used to because "we know all the easy stuff". And seems to conclude that we'll still be no better than religious shamanistic people once we "know all there is to know" and it still won't do us a lot of good.
It seems to be advocating give up on science now, with some rational like "while we're ahead".
I honestly don't get it. It seems like cloudy wooly thinking, bad arguments.
Sure, things are getting more complex and will continue to, but that doesn't mean we should give up, or that "it's mysteries all the way down". Every year we learn more and fix more problems. And we have to and always have had to make a lot of mistakes in the process. The author seems to think we're making more mistakes now and that's an indication the game is almost up.
I disagree, medical science is still churning out amazing breakthroughs, like HIV and cancer vaccines this year. And physics is still coming up with amazing things.
Just because it's getting harder doesn't mean we should stop or that we'll hit a wall and be able to go no further (and if we can see that wall coming we might want to think about stopping prematurely?)
Everytime we thought we'd learned everything we've been able to push on and learn more, discover more depth, and use it more to our advantage. I don't strictly speaking see why that has to stop just because it's getting harder. At least any time soon. Each new level also gives us better tools to work with.
And there have always been people saying we know enough now, or it's getting harder so lets stop now. And some have, and many haven't and that's why we still have progress. This is a age old endless reoccurring trend and bares the same ignoring it has always gotten. Or you can step off the train of progress and be left behind.
I do not think science is failing us at all in anyway. I think this article is poor on many standards.
