Software engineer feeling lost

I did my computer science like 10 years ago with focus on classical NLP and some exposure to computer vision and deep neural networks.

I pivoted away from machine learning and chose a more job friendly domain – front end development.

After 10 years, nothing is the same and feels like starting from zero. I want to get back/switch into AI/ML as a profession. Any advice? Thanks.

I am thinking doing kaggle competitions might give better exposure than going back to school or study a course 🤷
