How do I buy based AI?

Could you elaborate on the process of purchasing AI-based assets or services in the current market? I'm particularly interested in understanding the steps involved in making such an investment, considering the complexity and novelty of this field. Would I need to use a specific platform or exchange? Are there any regulatory considerations I should be aware of? Furthermore, what kind of research should I conduct to ensure I'm making an informed decision? Lastly, are there any potential risks or limitations I should keep in mind? I'd appreciate any guidance you can provide in navigating this emerging area of investment.
