I’m ignorant about AI and don’t want to be left behind. What is AI actually capable of that I should know so that I don’t get left in the dust?

This is mostly about AI’s capability to make employees obsolete and/or more productive and how I can actually leverage AI to make myself more valuable as it advances. What AI tools will help me be better at my job? What should I be taking advantage of to improve efficiency that I don’t know about?

I work in B2B and am mid-senior level (9 years experience)
