Not so fast. There is a company developing treatment for headaches with that technology and my wife has bad headaches. I don’t think the microneedles will be a problem. Can’t stick someone in the head with a hypodermic needle.
Recent research finding trillions of bits of micro plastic in every corner of the globe. It’s going into our food and water supply. Is it a health concern or hazard? Who knows, but it wasn’t there before.
I’m just saying beware of unintended consequences.
The headlong rush to EVs powered by wind and solar is fraught with many such unintended consequences that we are ignoring and will pay dearly for in the future. Problems range from the loss of our vistas to hazardous waste to soaring power prices making food unaffordable, to dependence on China. It won’t end well.
