#TrailheadTaughtMe I leveraged Trailhead to attain my Salesforce Certified AI Associate last year. Couple of things that impressed me the most. 

• The intense focus on ethical use of AI and the Trust factor - it makes up a significant part of the certification.
• The zero/low code investment Salesfoce has made to bring AI capabilities to all their customers and their use cases regardless of business size.

Well worth the investment!
