Yeah that phenomenon is called "proactive & retroactive interference". > For me, it seems like there's a sweet spot to remembering enough to know the concept and then relying on the internet to fill in the details as needed. I think i agree with you to an extent. For example, there is no point memorising all the digits of pie so that you can use it when programming, it's much more efficient to just remember what pie is at a vaguer higher level than to put the energy into memorising all its digits. But i would say that most people go too far the other way and only remember less than the efficient amount.
