Long post worth the read. I have a close friend who flies private jets. He flew Lear 60 for over 15 years and now flies a Gulfstream. This is a copy and paste of his response to me asking him if he thought Ice was the issue.
“We always fly in ridiculous cold temperatures.”
“Usually you get the bad ice when the temperatures are like 0 to negative 20. Believe it or not, there's a point where it gets too cold for ice. At negative 40, you pretty much can't get ice. Besides that, the airplane is equipped with hot wings and hot tail.”
“I flew the Lear 60 for like 15 years. It's a no joke airplane and probably the most dangerous airplane I've ever flown. It has a super critical wing. The airflow has to be perfect. When it gets into rough air and turbulence, it will easily stall. It has stalled on me at 41,000 feet just because we got into some turbulence. (On the way to Palm Beach as a matter of fact. ) we recovered and got her flying again around 30,000 ft. Scary
But here's the problem. This airplane has a terrible coffin corner. (At high altitudes) what that means is, you fly in a really narrow window where if you lose 20 knots, it stalls. And if you gain 20 knots, it goes into overspeed. The air goes supersonic over the wing and it goes into a high speed stall, or worse, a Mach tuck.
So if you stall, the normal recovery is to push the yoke forward to lower the nose and gain air speed again. At low altitude, you can push really hard and recover quickly. But in the 60... if you push hard, it will gain air speed and go into a high speed stall, it doesn't take much. It's very sensitive. The 60 has super short wings that don't make much lift. So then you high speed stall, and the computer is yelling at you... OVERSPEED! So then you pull back and enter a low speed stall. And you go back and forth trying to keep it in the air speed window.
This whole thing is pretty scary. And you should recover basically by using your finger tips using super small corrections. You can't over do it. If you try to muscle the recovery, she gets mad and will become unrecoverable. If she enters a mach tuck. You're done.”
“I taught the Lear 60 to other pilots and mentored them. I told them... this airplane has a soul and it's trying to kill you. Do not ever try to top the weather. Don't go over a thunderstorm. Go around it. If it means a half hour longer, then do it. Going over the thunderstorm will go into turbulence that you might not recover from.
These pilots went right over a thunderstorm. I think it stalled which caused them to drop down into the thunderstorm and ended up in mach tuck. They picked up so much speed that it ripped off the horizontal stabilizer. At that point... chuck Yeager can't fix it.
These same pilots did something similar a couple months ago. ATC got mad at them. They poked the bear one too many times.
This is not a beginner airplane. The Gulfstream would never do this. It has HUGE margins of error and won't stall like that. But then again... it's got HUGE wings. It's a pussy cat.
The Gulfstream is like driving a 4 wheeler. The Lear 60 is like riding a uni cycle.”

Funny how small actions, like calling someone, can be the beginning of something entirely new (or even change the course of your life)
Call THAT person. You know the one. It will be worth it.
I have dreaded calling people in the past. Waiting for the “perfect moment”. That moment never came and it was fucking stupid.
Just do it. You won’t regret.
Jensen reveals he first met the Founder of TSMC by cold calling their number off Yellow Pages
"I heard about this company in Taiwan, TSMC and UMC at the time. They were of course quite poor companies themselves, and they were barely making it."
"TSMC was probably about $300 million, something like that. It's a tiny little company. I heard about Morris Chang. And so I tried to call their US office."
"Back in the old days there were yellow pages. I looked it up, TSMC. There's a number there. I called their number and it's a recording. I left my name and my number and said a few things about NVIDIA: we're a new startup company building computer graphics chips. I called several times. Nobody called me back."
"And so I finally wrote a letter to Morris Chang. Didn't hear anything for a long time, and then one day it was 6 o'clock or something, this person called and said 'this is Morris Chang from TSMC.'"
"And meanwhile, everybody outside my office was playing video games and they're all laughing and screaming. 'Hey shut up! It's Morris!' I was so happy that the founder would actually call us back, because hey, maybe we won't have to die."
"And so we talked and he invited me to Taiwan. I came back to Taiwan, and that was the start of everything. Not just that partnership, but just the whole industry."
I've been traveling the world a bit. One of the most incredible experiences was getting to visit Taiwan w/ @JensenHuang. It was wild 🤯.. huge crowds of engineers, insanely good street food at night markets, and of course a lot of good conversations across many days. I caught some of it on video, see below. Alright, that's it from me, love you all ❤️

Technical moats are mostly over at this point. If you’re building something that is meant to be durable, the only moats now are:
• Proprietary data
• Network effects
• A physical component
