He&amp;#x27;s (not so) indirectly critical of Space X&amp;#x27;s Starship program and tribal groupthink. He may be &amp;quot;scared&amp;quot; of NASA because he&amp;#x27;s calling out one of their giant Artemis contracts.&lt;p&gt;Some longer takeaways:&lt;p&gt;- Simplify. We went to the moon 50+ years ago, but we are reinventing the wheel in some significant ways in Artemis. Why? We are supposedly going to the moon in two years, but we have never attempted a cryogenic refuel in orbit (this seems like a biggie).&lt;p&gt;- Communicate a lot. Why aren&amp;#x27;t people talking about the seemingly giant increase in complexity to accomplish the &lt;i&gt;same&lt;/i&gt; mission we had in the 60s (land on the moon)? People need to have safe&amp;#x2F;comfortable way to raise questions and concerns.&lt;p&gt;- Have many layers of redundancy. Apollo had 6-7 backup procedures for what to do if they couldn&amp;#x27;t launch the lander off the moon.&lt;p&gt;- Test. small tests, big tests, real tests, skin-in-the-game tests. Some tests can be eliminated by simplifying or, in the case of big systems&amp;#x2F;tests, doing small tests on the riskiest components.&lt;p&gt;- Humans have ingrained biases. Will be situations astronauts haven&amp;#x27;t experienced where their instincts may be wrong.</text></comment>
