A question posed to Quora asked, worded a different way, about which programming language to learn for long-term success. The post showed up in my email and I decided to see the detailed response. When you read it, remember that money should not drive your efforts. Your vision and the value you can create should be at the core.
As I read the answer, I sensed I had read it before. Maybe from a Forbes.com article citing Quora. A quick web search revealed nothing as of this writing. What I realized this time around was who wrote it. Carter Page of Google, who appears to be working on the BigTable data storage system. Anyway, his answer received nearly 2,000 votes. The wisdom he shares is to learn the skills behind the skills.
