Sans cannot be Ness because Sans is Gaster's son.
Simple as that.
Anyone with a bit of inside knowledge to Undertale can disprove most of Matpat's points in the video.

I have to admit, he made some good points in the video. The fact that Ness talked about a world where everyone has their own font definitely is an inspiration for sans and papyrus, but just that doesn't sans and ness are the same thing

*doesn't mean sans and ness are the same thing

I never saw any good points in his video.
Just small references.

SANS ISN'T NESS!! TWO REASONS! 1: HOW DOES SANS SPEAK IN COMIC SANS?! 2: COPYRIGHT!!
