I'd have to say yes, or at least definitely in their current form. I just returned from 4 different comic stores trying to find one issue that came out last week! This highlights just one of the many problems currently with comics, the death of actual brick and mortar comic shops. I remember (and I'm not that old!) when I could walk down to the neighborhood comic store, say hello to everyone, and pic up my weekly fix. Nowadays, the only real option for getting comics is to order online. Issues are print at such a low run that unless you order then MONTHS in advance you have absolutely no chance of picking them up. This means that new comic readers don't have a chance to actually try out new, well written titles. Couple this with the fact that prices of comics are rising to such ridiculous levels that there is no new market for undiscovered readers (you're going to have a hard time convincing a kid to spend $3 on 22 pages when he can get a video game for $30 or so). With all these problems it's sad to say I can't see comics being around for the next 50 years.
