Algebra helps you solve real-world problems that you will face when you are on your own.
Matrices are tools to solve linear equations. Engineers use matrices in solving electrical problems in circuits using Thevenin's and Norton's theories.

Can't help solve problems.
There is no way of knowing if new technology will solve world problems since we have no way of knowing what new technology is going to be developed, or for that matter, what world problems will exist at the time that technology is developed. It is possible that new technology will be used to solve world problems, and it is also possible that new technology will be used to make world problems worse. We will have to wait and see.

William Steward Burroughs invented the calculator because he wanted the world to know hot to solve equations and problems and figure out how to correctly do a math problem. he also wanted you to always get an answer right when using a calculator
