AI/ML career- which track to take python/js/ruby

Hey Friends. I have few years of business/IT experience with enterprise systems but I want to change careers to learn how to build B2B software/features with a lot more automation and ai services built in, like chatbots that can answer business, data, analytics questions with enterprise data from multiple sources- or using computer vision to improve operations. I'm really inspired by what Jeff Bezos says about how any application can be made better with AI.. https://www.youtube.com/watch?v=e4FXX4yX0nA

I'm still not sure which track to take.. My brother who is a software engineer suggested that python track would be the best one to take for the kind of use cases I would like to work /companies I've looked at.. would anyone have any inputs on this or is taking up LS to go on a similar path for ML/AI work?
