跨领域寻找服务不足的交汇点

"I have experience in [field 1] and genuine interest in [field 2] and [field 3]. Most people in my world only know one of these. Identify 5 problems that sit exactly at the intersection of all three that are currently underserved. For each one, tell me: what the problem is, why someone with only one of my backgrounds would miss it, and what I could see that they cannot. Be specific. No generic career advice."
