Whole sector shrinking, should I change fields? after 18 years as a software tester

Many of the people I know in my field were laid off this year, including me as a software tester. I have read a lot of threads here and could not find my exact situation. I am open to a pay cut if the field is stable. Which areas are hiring?

Talk to people in the field you are considering. Two coffee chats changed my mind about one option.
