Advice for mid-level experienced professionals

I am an IT professional with more than 15 years of experience with product development and business analysis experience. Data Science has always fascinated me and “Foundations of Data Science” course has given a new purpose and made learning exciting again for me.

Since I am in product development on a fairly mature product, i do not see any opportunities for working in Data Science in near future. So far a person like me who also has interest in DS, AI and ML apart from learning, how can I continue to be engaged in this field. What should I do to make sure i continue to improve and sharpen my skills related to DS, ML and AI even though i may not have opportunities to apply in my career for a foreseeable future.

This input would be very useful especially for mid-tier IT professional like me.
