Do we really need to hire designers in today's world?

I know that ecommerce is growing and so is the need for designers, but do we really need to hire some graphic designing company UAE to fulfill our designing needs when there are so many free templates and tools available online? For instance Canva for once is a crazily amazing app providing ready made template for every purpose, event, etc. One can even make a great use of its free version let apart the premium one.
