They become available everywhere in templates, layouts, and partials, it can cause problems with complex or and nested templates. @not_assigned_ivar returns nil, “locals” tell you that they are not assigned. This is two main reasons why I trying to avoid using instance variables to pass data into views templates.

Don’t get me wrong this is just the case for Rails controllers and templates, memoization is the great technique.

Absolutely agree with your thought here. I will think about it.
