Is latest a contronym?

Is latest a contronym because it could be used to say "the latest iphone" or "bob was the latest person to arrive art class"

Why do 20th century born people say their century is better than ours?

I was born in 2000, I love laughing at people born before me!

Anyway, these dummies now says the 20th century is better than my century. Ha! No.

Their century has: WWI, WWII, Vietnam War, Korean War, so many wars!

My century has: Social Media and iPhones

I just don't understand why are they full of cancer! How sad!
