Business Cards

So, are business cards still relevant. Saw a linkedin post suggesting that they arent, and your email signature is enough.

I may be old, but I think they are still relevant and its not just my Patrick Bateman side saying that.

Oohhhh, bone paper set in silian rail. If it has a watermark, I'm definitely calling.....

EDIT: Part of this is an honest question so stop downvoting me.
