It's less efficient to learn how to do something than to have somebody who knows how do it for you, but it's more effective to learn for yourself. Hard won knowledge is rarely lost.
I totally agree. There are exceptions to every rule, but random people on the internet who you aren't being paid to solve the problem for by a very large majority would benefit more from education than having their problem solved for them.
Yeah but it's funny in a different way; they are giving ignorant and condescending advice because while big cats have impressive hunting abilities, they don't normally hunt mice.
