I am a physician turned drug developer and work in biotech now. I have also dabbled a bit in IT though and got hooked on HN many years ago.
I keep coming back to HN for the thoughtful comments and nearly complete absence of malignant ones.
I'd argue that quality of discussion has gone down. It has become a lot more emotional, less forgiving and less politically diverse. But, I tend to criticize more things than I praise.
I work in IT but I love biotech. It was (still is) my dream.
Got into IT due to circumstances.
Some day I am gonna FIRE and invent cool weird plants.
