I just visited the Chocolate Lab at ICE, for a half-hour intro to what chocolate making looks like. It's hard to imagine that this is going to become a thing for most chocolatiers. Certainly not for pastry chefs. There must have been $100,000 worth of equipment in there, and it filled a room. Beyond that, chef Laiskonis said his takeaways were that "making chocolate is easy. Making good chocolate is really hard." The other takeaway: "90% of chocolate making is janitorial."
It would seem the reason to take this on, besides being obsessed—in which case on one's going to stop you—is if you have a particular vision for the flavors you want, and none of the commercial makers are delivering. I don't think you'd do it just for the quality. It's doubtful you'll outdo Michel Cluizel and Amedei.
