Irwin and the Lions,
The only lions I ever saw were in the zoo and a few in Zimbabwe(at a safe distance).
As to the purpose of an AIM-system it presents only a way of creating automatic trades about which you do not have to think. In that sense it is like a washing machine. But if you put hydrochloric acid in it instead of soap it will not clean the clothes. So its operation requires something more than blind reliance on the system. Maybe the analogy is not quite right but it means to show an AIM should be used with proper attention to its purpose.
Using an AIM does not mean that one can not add all sorts of additional systems next to it to do better, or to override the AIM, if the need arises.
As to your reference to reinventing the wheel, it does not apply, or rather it is a poor analogy. Think of the high-tech wheels we have today and compare then to the wheels that the barbarians had. I say reinventing all sorts of wheels has been worth the trouble, and reinventing all sorts of AIMs also has paid off.
