Often, this can depend on the type of role you want. To illustrate, if you wanted to work in AI sales, you would have to understand the product enough to sell it but you are not required to have the same expertise as an engineer or software developer. For the most part, learn more about the current and future landscape for AI careers. Then, take a look at some of the roles which are currently and/or will be in demand. Read the job requirements in the job listings of your preference, and begin your career journey following those guidelines.
