That is like saying that a computer should play chess the same way a human does.

Humans make mistakes, forget, and have limited time to crunch numbers. So, we have methods to help us do things. Computers do not have these shortcomings, and thus can do things that we wish we could do. Also, there are patterns a computer can "see" that an unaided human cannot.

Computers are not just there to implement human algorithms as if they were macros. They are game changers, and should be used as such. Not that everything you do without a computer should be thrown out. Keep what works best, but make sure you utilize the computer for its strengths, not just its speed.
