What are your thoughts on the best way to go about introducing AI and Machine Learning technology in your company's processes? Do you think it is absolutely necessary or preferable to hire an external professional or company, or do you think having your own IT department widened to include an AI specialist could also reap good results?

What would be the challenges in hiring an AI specialist if you wanted to hire one to be a permanent part of your team? I'd love to hear from someone who has had experience in both scenarios, and from AI specialists what their point of view is, thank you!
