VC firms are not really capable of anything purposeful: they're here to find a discount, which helps the company return a premium: they're a symbiotic parasite and whatever the culture they foster, when discount is hard to find or when premium look gigantic, well they jump on anything forgetting that finding a discount in a difficult period or a gigantic premium is a red flag.
But do you expect parasites to start thinking ? They cant.
Sequoia put in their own website that the FTX CEO was playing a video game while pitching hundreds of millions of investment. The same firm would kick me out of the door if I went without a tie to interview for a secretary job.
Difference is that I dont promise a huge premium at a huge discount. And it's a red flag for any sentient when someone is distracted in a high stake conversation, but not to the Sequoia parasite only eating premiums.
