Wang is a networking machine and has connected with everyone in the industry. Likely was brought in as a recruiting leader. Mark being Mark, though, doesn’t understand the value of vision and figured getting big names in the same room was better than actually having a plan.
Your last sentence suggests that he willingly failed to take the choice to create a vision and a plan.
If, for whatever reason, you don't have a vision and a plan, hiring big names to help kickstart that process seems like a way better next step than "do nothing".
Wang is not Zuck's first choice. Zuck couldn't get the top talents he wanted so he got Wang. Unfortunately Wang is not technical, he excels in managing the labeling company and be the top in providing such services.
That's why I also think the hiring angle makes sense. It would actually be astonishing if he could turn technical and compete with the leaders in OAI/Anthrpic
You’re right – the way I phrased it assumes “having a plan” is a possibility for him. It isn’t. The best he was ever going to do was get talent in the room, make a Thinking Machines knockoff blog post with some hand wavey word salad, and stand around until they do something useful.
