It depends on what field you’re studying. Some fields of study, like social studies, move very quickly. So it’s not uncommon for someone studying one of those subjects to exclude research that’s even 10 to 15 years old because things move so quickly.
A different subject, say hydrologic engineering has been studied for hundreds of years and doesn’t change very quickly. So a publication from 1994 could be just as valid today as it was then. Every topic is different and without more context the meme as is, is just meant to incite a reaction. Not to tell us about something that actually happened.

I study social study and frequently use papers that are referring to Karl Marx. Or feminist literature from the 70s. Or black literature from the 60s.
