[@rkf053fitz]

It's one of the pillars of Stoic philosophy. Why worry about things you have no control over?

[@EnthalpyAndEntropy]

@@rkf053fitz two reasons. First, a lot of folks lack the wisdom to know they don't have control over certain things, especially now in the US. Furthermore, even if ego and hubris aren't a problem, anxiety disorders are a thing. Second, as an engineer, I worry about stuff outside of my control because it can have an effect on what I do control. When making a plan, I know success is never guaranteed, i.e., it's out of my control. I do, however, often have control of how I fail when or if I fail. I can take a path that should I fail it guarantees a certain effect and can preclude other, worse effects that could happen if I chose a different path. It's for this reason, unlike Destin, I'm unfortunately incredibly bitter and hold copious amounts of contempt for people in general. There are a great many "unavoidable accidents" that are actually avoidable and incredibly reckless.

[@stretchwookie]

I would just like to point out how brilliant this video is. Every time Destin's camera overheated, he could have just edited that out and continued the interview. Why didn't he do that? Well , he had a couple of choices. Instead of showing us ads or only talking about how embarrassing it was, Destin chose to continue to educate us and bring more related knowledge into the picture. Chef's kiss. Flawless execution, Destin.

[@myalakee7329]

I watched this video with huge excitement and interest. I was inspired with owe with the brilliance of space science and its creative engineering and even more with the knowledge, humbleness, and wisdom of Dr. Mather! What an outstanding human being he is! Our earth needs more people like him. Since the launch of James Webb, I've been following its journey and have learned a great deal about the science behind it. I have to admit this video is one of the best videos I have watched discussing the Webb. Your simpler explanations above and beyond what Dr. Mather discussed are excellent. Please have more videos on this topic. Well done.

@BrightForest it also means he can see which parts might need more explanation for the average person, or which parts need simplifying or an analogy.

Amazing conversation. The best thing about this is the way that Destin and Dr Mather have been able to break it down for simple noobs like me. I really liked the way they talked about the Lagrange point and how the light in visible spectrum can expand into infrared spectrum and how the light in infrared spectrum can travel through space dust. Thank you for this. Looking forward to see the beautiful images that are going to going from James Webb Space Telescope.

It is the wonder of engineering and science that our heroes are so calm, like Dr. Mather. But what also struck me was how excited he clearly is by this mission -- there are a couple of spots where his eyes light up and he gets animated explaining something. I have been an engineer for 35 years and I also find great excitement and delight in learning and understanding complicated things. What a wonderful career science and engineering is!

I graduated 8th grade when this project started, and here I am in my mid 30s in awe by the scientists and engineers who make this possible.

Those people will believe the Earth is flat even if we shoot them up there with the JWST because they can't see the other side of the Earth at every given moment.

"I don't get anxious about stuff I can't deal with." Truly a wise man. I've been looking forward to the JWST launch for at least a decade and have always been nervous about it potentially failing. If minds like that of Dr. Mather are in charge, then there's very little to worry about after all. Can't wait!

[@MountainFisher]

"in 2011 after wasting over $4 billion their budget was cut for "billions of dollars over budget and plagued by poor management" so it's no wonder Mather doesn't want to take credit for being in charge since almost the beginning. Because the runaway budget diverted funding from other research, a 2010 Nature article described the JWST as "the telescope that ate astronomy". Well after Congress cut it the astronomical community led by a Congresswoman ran a publicity campaign for why taxpayers need to pay for their research toys and they've gone up another $6 billion since then. The reason you put real managers in charge and not a Nobel Laureate who doesn't understand that the money has to come from somewhere. SETI after losing taxpayer money acquired the funding they needed, but they stopped having so much waste.

Amazing interview Destin. What a brilliant and articulate man. I love how he he is quick to credit all the other scientists involved before taking any credit himself. That is truly a mindset that serves humanity. Besides the incredible science the most valuable thing I learned from Dr. Mather was his wisdom of “letting go”. Knowing that once you’ve done your best there’s no upside to worrying is a lesson we can all apply to our everyday lives. That was beautiful.
