If a machine can do it, then spending a lot of time on learning how to do it, is not particularly fruitful.
Therefore, every breakthrough in technology invalidates entire textbooks.
The machine can do it. So, stop wasting your time on endless exercises on doing the same.
For example:
How much time should you spend learning how to manually solve this system of equations?
x+y=5
2x-y²=7
Not too much, I am afraid:
$ maxima -q --batch-string="solve([x+y=5,2*x-y^2=7],[x,y]);"
(%i1) solve([y+x = 5,2*x-y^2 = 7],[x,y])
(%o1) [[x = 8, y = - 3], [x = 4, y = 1]]
You can learn how to use the machine.
You can learn how to program the machine.
Unless you want to be unemployed, stop learning how to be the machine.
