The last three years of my work will be permanently abandoned
I work in the field of Data Science and one upsetting reality has started to sink into my mind over the last year.In a business there is top line and bottom line.  There are a lot Statistics/ML/Data Science jobs that are about moving that bottom line.  You build something to optimize something to reduce costs.The value provided by the bottom line people is less visible than the value of top line people.  The easiest way to move the move the bottom line is by just getting rid of people.  So when the axe falls the bottom line people get cut and it's hard to understand why.It's the same thing as people say about fires.  When you put out a fire you are a hero.  When you prevent the fire in the first place, everybody thinks it's business as usual and nobody understands why you are needed.
