I’m a specialized engineer, R&D nuclear/military/chemical.

Oh I agree with your skepticism, but your wording comes off as crazy. You could express healthy skepticism of this with much more tact, so I’m very surprised someone at your level has your grammar, which is rudimentary, so people are assuming you’re not very smart. It’s the subtext to your comments.

If you word more carefully, and stick to short specific skepticism, you’ll be received better. You criticized the progress of science in general, which is odd to do. Not specifically the uncertainty.
