I'm really skeptical of your argument. To start with, you mention that many presidents majored in History-- but the prestige came from the law degree that followed, not the history B.A. (which maybe is popular due to history's focus on political events).

Secondly, you suggest that the study of History centers around high level decision-making. I'm not really sure about that. Assuming you're right, this is also the case in business school, where the decisions being analyzed happen to concern private enterprise rather than the government.

I do like your point about the relevance of Silicon Valley history. But I suspect that it's much more important to be obsessive and passionate about a piece of technology than to know the story behind previous attempts. Palmer Lucky rebooted VR with incredible dedication to the product, not an academic understanding of the field.
