Testers to programmers is like cashiers to cooks at Mickie Dees. I think you are resentful that your job can be automated and thus, the value of what you do is quite low.
I believe the implication is that most of the cashiers will be completely replaced before it is worthwhile economically to try to reduce the number of cooks.
Testers are like McDonalds cashiers. They will eventually assimilate with the self checkout. Now, they may be able to get a job servicing the soda machine if they count their blessings.
