"researchers foresee the possibility of using the approach in patients 10 years from now."
How can medical research move so fast and so slow at the SAME TIME?
That's easy. It's all about the funding. Now some VC will sink a ton of money into this, after which the pace will slow to glacial while they await regulatory approval. Right about when they need more money, they'll announce another breakthrough, or something favorable enough to secure more funding. Eventually some newer idea will knock this one off its pedestal, or they'll ship a product and get bought out by a large pharmaceutical or medical device company. The doctors and engineers will be free to repeat the cycle once their options have vested.
