Do I need Powerpoint?

In lieu of my recent and thrilling discovery of this very presentation-assemblage interface, I find myself wondering if I even need Powerpoint. Do I? Potential answers are organized in a bulleted fashion below.

I probably do.
I'm still pretty shocked it didn't come already installed on my computer
Wouldn't it be great if I did my first pizza talk with this?
Yeah!
I guess I'm kinda up in the air about it

In retrospect, those weren't really answers at all. More like musings. But this isn't Powerpoint, so I think everything is pretty chill.
