Hawking:

Philosophers have not kept up with modern developments in science. Particularly physics.

Tyson:

the 1920s come in, we learn about the expanding universe in the same decade as we learn about quantum physics, each of which falls so far out of what you can deduce from your armchair that the whole community of philosophers that previously had added materially to the thinking of the physical scientists was rendered essentially obsolete, and that point, and I have yet to see a contribution

philosophy has basically parted ways from the frontier of the physical sciences, when there was a day when they were one and the same. Isaac Newton was a natural philosopher, the word physicist didn’t even exist in any important way back then. So, I’m disappointed because there is a lot of brainpower there, that might have otherwise contributed mightily, but today simply does not. It’s not that there can’t be other philosophical subjects, there is religious philosophy, and ethical philosophy, and political philosophy, plenty of stuff for the philosophers to do, but the frontier of the physical sciences does not appear to be among them.

Seems to me they are saying that inferential distance between philosophers and modern physics is too big, so unless philosophers start seriously studying physics, they will no longer be able to contribute meaningfully using their intuition only. (Of course they can still provide some Deep Wisdom, or post-facto explanations.)
