Is the message going to be written in English?

I found the following movie trailer interesting.

INTO ETERNITY “THIS HIDING PLACE SHOULD NEVER BE DISTRUBED” Cum Diner: The Best Sex Tube & Porn Videos | 100% Free

“It is an open question if and how we can communicate with an unknown and very distant future about complicated issues like nuclear waste and radiation.” Cum Diner: The Best Sex Tube & Porn Videos | 100% Free

It looks interesting.

Will there still be human beings around in 100,000 years? If so, will they still have a need to be able to read? Should we perhaps stick to symbols for warning signs?

I wonder if the skull and crossbones sign can convey the same clear message in 100,000 years.
