All I got from the article is that there are various work culture environments and experiences that the signature archies of the future will come from, and they reflect those factors.
Coming from a high output production firm like APdesigns, they were fortunate to get exposure to more work and diverse client requirements - obviously a luxuary. But, their own sensibilities will shape them in what they learn from greater volume of exposure. Like the fellow who says his first turn-on was to see the gated community, with waterfall, perfect sand bunkers, lush green FW and greens at the Vegas course and think.... that is what he wanted to do. Then after the exposure and some experience, his sensibilities (unknown if it is just trend following) gravitates towards wanting to do 'more is less' theme projects. Or the guy that started with First Tee modest projects where all he had to work with is turf and some soil, and then got the chance to work in multi big budget projects.
At the end of the day, these younger archies will evolve to whatever their work culture reflects and their sensibilities and personalities project into their own futures. I'd say with all the mega projects they get to become involved in at the big firms, they will have an advantage only restrained by their own ability to evolve and learn. They can either go out on their own and become their own signature in a botique firm, or evolve in the shadows that reflect the big mother firm. Like all the future archies, the economic growth or lack thereof in the design construction arena will determine stagnation or advancement in the craft/profession of GCA.
One thing I wonder about, if work environment and culture have a bearing on future design concepts and quality of designs, is if people like the Mexican course laborers - who have been on the nomadic trail moving from one construction project to the next, would have any breakthrough insights if they were given free reign to come up with a design based on their cultural and work experience perspectives.
Do any of the archies out there, ever ask them about their ideas? With all the Mexican and migrant golf course construction laborers over the last few decades, there must be a few who have been at it for a long time and have seen nearly everything in the way of techniques and problem solving in the ground, and have their own sensibilities and ideas of how to do things.
