Passive income: NO

Starting an AI product research and validation service can potentially lead to passive income, but achieving true passive income may not be common for most people. To make this hustle passive, one would need to set up automated systems for research, validation, and client communication. While some individuals may reach a level of passive income through this hustle, it often requires ongoing effort to maintain and grow the business. It is more likely that a combination of active and passive income streams is needed to sustainably earn from this service. Misleading expectations include thinking that passive income can be easily achieved without continuous effort. Overall, while passive income is possible, it may not be the norm for most individuals in this field.
