When I first got a job, I asked the company okay, how many people are going to use the code i write?
If the answer wasn't in hundreds of request per seconds, i wasn't interested in job.
I found job at ad tech companies, pay wasn't any good but the challenges were immense.
Most people write code, which will hardly be run by other people or even receive any customers.
One of the products my employer builds is used twice a year. People pay tens of thousands of dollars for the privilege of using it twice a year. It's tremendously valuable to be used twice a year.
Value and use are not always synonymous.
My wife uses me twice a year.
