Hi. I am curious about this. Most advances in tech that I have seen and/or heard about have some kind of ties to computers- smartphones, tablets, streaming services, video sharing sites, social media, apps, and things like Siri, Alexa, Google Assistant, etc.
What non-digital tech advancements are there? There are a few things I can think of. There are electric vehicle charging stations. There's one in the parking lot of the local plaza where I grocery shop.
Scientists have figured out how to create solid light crystals:

We have DVD rental machines/kiosks and flying cars are in development.
There are certain new types of health supplements that I am familiar with.
Please help- thank you.
