I say no.
The Mayans failed to forecast their own demise, so their predictions lack credibility. Anyone who claims to believe the world will end tomorrow and who had not maxed out their credit cards and cashed and spent their IRAs also are not credible to me.
There’s a long and colorful history of end of the world predictions, and every one has been wrong. So far.
I plan to write a “I’m alive, Mayans” post tomorrow. Should the world end, I won’t. No one would be here to read it.
