I knew about these tablets in the 1970s and told people about them. They thought I watched too much scifi. My step daughter is a nurse. I've told her about many new tools to come for the industry. She is in charge of an ER. So I gave her a heads up on what becomes common in the near future. She knows what new tech to purchase to save lives better.

I'll give you an easy one. You know those wiring harnesses they put on you to get your eeg? Soon they will be a thing of the past. They will use Bluetooth to send the signals back instead of wires. I've told her of a dozen more. That was just the most obvious.
