I'm going to assume your comment wasn't as mean as it appears in writing.
Why am I here? Because I started my first business in college, then went into finance to get some 'real world' experience, and then went on to start several other businesses (both tech and finance). I've employed quite a few people over the years, had some good times, some bad. You know : The basic entrepreneurial story. I started programming with 6502 machine code, C, C++, Perl, and more recently Python, Scala and GPUs. Will likely start something to do with deep-learning/NLP in the New Year. HN feels like home. That's why I'm here.
As to the content of my comment : It was intentionally low. I wanted to see how many negatives a valid comment about actually being in the finance industry would generate (-2 after a couple of hours, constant since). And, besides, any person in the finance business would immediately smile at the clear-cut upside/downside evaluation that is so common in the business. I just said it out loud.
