So you're going to always only do numerical computations only? Good luck solving even simple optimization problems that have a few parameters.

Who needs calculus anyways? I'd rather focus learning linear algebra especially after realizing a derivative is just a linear transformation and integration problems share a lot with determinants (areas).

Maybe so many more people would engage with mathemathics when they realize this.

I can't really think of anyone. Maybe just mathematicians, physicists, economists, computer scientists, chemists and engineers. Apparently they even use something called back propagation in AI training, which is nothing but chain rule from ... calculus.

But yeah, I can't see it being relevant since we have linear algebra already.

Applied calculus doesn't need infinities. No computer can represent a real real number. Only truncations of them, only finite versions of them.
