If you're a game collector and I show up with a rare game, you're probably interested. Even if you don't buy it, at least I'm not wasting your time. If I show up with an Ethernet switch ASIC, you're probably not interested and I am wasting your time. That's why Marvell would cold-call Juniper and Cisco, not Antonio Romero Monteiro.
You know, I thought about this overnight. I'm pretty sure I feel this way partially because talking to people real time isn't free for me, it has a cost. I have to mask neurodivergence all day to get along in the corporate world, I do not want to put the mask on again unexpectedly when there's a knock at the door. It's my off time, it's like getting paged or something.
The second part is the privacy aspect, I don't want to do business in a power asymmetry -- they can reach me where I sleep but I cannot do the same to them. I don't want anyone I engage in a business relationship with to get any ideas of any type about who/what they see at my home, from judging negatively to jealously to planning to come back and take it. It's unnecessary risk surface for a business transaction.
