I am mid-career chemical engineer looking to learn some skills. I have strong background in projects and design engineering. Just thinking if I need to make a job change in next 5 years, what are the top skills needed for the future? I learned a bit of SQL in a previous assignment, wondering if I should spend time learning more programming languages and AI related skills? I love learning new things on the side, but I just want make sure I spend my time and effort on something worthwhile.
