Maybe they'll replace treestand for out of shape old coots or for people that have untampered lands to hunt. But, for the majority of us, there's nothing like 20 feet up on a frosty morning. There's nothing like the mobility of a climber or hang on. They may have there place if you want to use them, but you can do just fine or better from above. They're obtrusive and bulky. A blow down or a couple strategically placed clippings will do the same job. They're not the way I like to hunt.
