For me the big issue is Mark insisting on holding on to the case that this was a good investment.<p>Last time he insisted on calling out the non-believers about tech. This time, he only writes a couple sentences defending the tech and is laying the groundwork for abandoning the physics and just supporting the team.<p>Something like.. &#x27;yeah, we took a chance. Someone has to. It didn&#x27;t pan out, but the team is great.&#x27;<p>I have done my share of pitching the VCs and they have to uphold the image that they are the  smartest people in the room, or else what are they? Just Money who can&#x27;t possibly know everything about everything? No! can&#x27;t be.<p>So, here is a smart person dispensing advice on all things life, entrepreneurship, investment and technology who is clearly been had and out of his depth in this particular field. But smart enough to know that he&#x27;s been had and the only remaining way out is to abandon tech and back the team.<p>This is a personal issue for Mark and has nothing to do with science and the rest of us. The science is clear. He just can&#x27;t admit that he was had, because that kills his standing in his day job.
