Ok, first, it only applies to Type 2 diabetes.

In a remarkable medical breakthrough, Chinese scientists have successfully cured a patient of type 2 diabetes through an innovative cell therapy approach.

Second, it was done on a case-by-case basis. Each person has their own therapy tailored for them. This does not appear to be a mass-solution.

The groundbreaking treatment involved transplanting lab-grown replicas of the patient’s own insulin-producing islet cells into their body. This ingenious approach effectively restored the patient’s pancreatic islet function, enabling the body to regulate blood sugar levels naturally without external intervention.

From the linked article:

According to a South China Morning Post report, the patient underwent the cell transplant in July 2021.

The new therapy involves programming the patient’s peripheral blood mononuclear cells, transforming them into “seed cells” to recreate pancreatic islet tissue in an artificial environment. This approach leverages the body’s regenerative capabilities, an emerging field known as regenerative medicine.

You give your top talent what they want. The problem is that they hired a consultant to find out what that was. The consultant, knowing on which side his bread was buttered, told the board what they wanted to hear, which is, after all, why they hired a consultant instead of just asking.

There was a discussion a couple of years ago around gasoline taxes and how they are supposed to pay for roadway maintenance. The question came up about EVs. There were discussions about how to include EVs in the taxation system so they would pay for their fair share of the road. One of the options was to impose a tax attached to your vehicle registration based upon the weight of the vehicle. The greater the weight, the more wear and tear it produces on the road surface. This might be one solution to the barrier problem, namely moving the extra cost to the reason for the extra cost.
