I think you should. People are always attracted to new shiny objects and most folks don't understand the complexities of blockchain and AI. While I think it's worthwhile to educate your management team, I think the best way to do this is to align their blockchain / AI aspirations to core competencies for your company.
Deploying technology for technology's sake is a problem I see often--this comes down to people's attraction to new shiny objects; and it's extremely important to make sure that this tendency doesn't have a negative impact on the core business. I work for a leading AI and blockchain behemoth and I see this all the time--quite honestly it benefits my firm's sales but it's a massive problem for shareholders.
My advice for most leadership teams is to focus no your core business. Blockchain and AI are all the rage right now, but they are complicated to implement--especially in production! AI systems are very brittle and AI-Ops is not simple. There is a great paper from google titled "Machine Learning, the high interest credit card of technical debt", I suggest you have a read.
In terms of your company, if you believe these solutions will improve your core competencies and provide a competitive advantage then you should absolutely invest in these capabilities. However, it's really important to get the basics right before moving onto fancy new technologies that aren't well understood.
There is a great meme/cartoon that I like to show folks that depicts a teacher and a few students in a class where the teacher is demonstrating basic arithmetic on the blackboard and one of the students raises their hand and asks "when do we get to machine learning." I like to use this cartoon when I discuss these types of solutions because it helps me to put things in perspective.
