Some degree of informational amensia is a good thing. We've all hit the "I need to do X, but every page on google tells me how to X in Version N-1, and it doesn't work like that any more".
I don't understand your example. How does "informational amnesia" help against "I need to do X, but every page on google tells me how to X in Version N-1, and it doesn't work like that any more"? If you can't find a solution, you should ask on the Q&A channel, regardless of informational amnesia or not.
