As much as I want to see pipe smoking become more popular and expand, within reason, I don't see the OP's prediction coming true, at least in the sense he means.
Pipe smoking is the most niche form of tobacco usage in the United States. According to a national survey done by the NCBI, pipe smoking barely makes up an entire percentage point as the dominant means of using tobacco among tobacco users, a demographic that has broadly been shrinking for some time.

There is very little reason to see these trends change.
First, and I say this with love and respect, but pipe smokers tend to get so sentimental about their hobby that it interferes with their ability to think clearly about it. We have a tendency to romanticize the peace and calm it brings us, and think our indulgence in this hobby is in itself reflective of not just an individual, but a collective, desire to rebuff a world that demands too much of our time and effort. That may be true for us, and that general feeling may even be true for many, but that doesn't translate into business success. There's much to be enjoyed from pipe smoking, but its pleasures are not a monopoly, and similar amusements are readily marketed by the very entities that have cultivated the malaise they seek to address.
Then there is just the brass tacks of costs. Tobacco is costly. Pipe tobacco especially so. The price of entry is high. A decent brand new baccy pipe will run around $40-100. Average 2oz tin about $10. Don't forget your cleaning supplies and tools, the former of which you will need to replenish constantly. Local, state, federal, and even international guidelines make it an expensive industry to manage. And the overwhelming negative view the general public holds of the tobacco industry (which is largely justified, mind you) makes it one of the few easy targets for regular tax hikes. Pipe tobacco can be enjoyable on a budget, to be sure. But by and large, there is a reason so many pipe smokers are retirees or middle-to-upper class types: they can afford it.
Speaking of the negative view the public holds of the tobacco industry, it is a view that doesn't seem likely to change. And for good reason, as much as it pains me to say. Cigarettes and rub are little more than nicotine delivery devices in the guise of a tobacco product at this point, and the profit-driven reasons for that should be patently obvious. The next big thing, vaping, is quite literally a nicotine delivery system and little else. Given nicotine is considered a highly addictive carcinogen, that instills distrust, and justly so. Moreover, many cigs and rub users (not all!) do a fine job of presenting a bad image: a constant stream of litter, spittle, cancer, and smelling like dead ass do little to broaden appeal. I've seen countless surveys where those polled will state with conviction that they would not date a smoker. Cancer and not getting laid? That's a tough sell. I understand many of these criticisms don't apply to pipe tobacco per se, but as a tobacco product, they are lumped in this, and that is all there is to it in the public eye.
Finally, pipe tobacco has been in a long decline in use since the 1970s. There is not reason to believe that such a long and steady trend to reverse itself. There may be some minor surges in popularity that successfully manage to target certain demographics. But it will never come close to its golden age. But that's okay, I think. I like that this is niche. I want it to be healthy and the (good) purveyors of this hobby to make a decent profit. I also want this hobby to be at least somewhat affordable, relatively speaking. At least in the United States, it mostly is. Smoke 'em if you got 'em. Because there is no going back to the so-called glory days.
