Strange that a bunch of aerospace and mechanical engineers believe it is

It's not that strange. There are lots of people willing to con others out of investment money.

who probably doesn't even work on STEM

You're wrong there

I can't tell if you genuinely think you're smarter than these people or if this is just the classic "space craft are stupid!" Rhetoric that's become popular since Musk started SpaceX.

I don't think I'm smarter than these people. I think I'm smarter than the people being conned by these people. Spacecraft certainly aren't stupid. A lot of what SpaceX has done in spite of Musk has been amazing to see. Their rocket engine development is some of the coolest stuff out there. It's too bad that the company is led by a con man who makes grandiose claims that they'll never live up to.
