What are limitation of karnaugh map answer?

Karnaugh maps (K-maps) are limited in their practicality for simplifying Boolean expressions as they become unwieldy for more than four to six variables, making it challenging to visualize larger systems. Additionally, K-maps are not well-suited for automated digital circuit design, as they require manual input and can be time-consuming for complex functions. They also do not account for don't-care conditions effectively in some cases, which may lead to suboptimal simplifications. Finally, K-maps can be less intuitive for those unfamiliar with visual methods, potentially hindering understanding for some learners.
