The "accurate predictions from the past of scientific advancements" thread

First, here's something I've just seen:



Absolutely all of it is 100% correct:

• We carry phones with us today
• We have watches that can be used as phones
• We can call people simply by asking the phone's built-in AI to call a person in our contacts
• We can use Facetime and the like to engage in video calls
• We can use apps to translate languages from one to another in real time, as they are spoken

That's a hell of a good prediction.

I thought this could be an interesting topic, where people post predictions of future technology from the past that have ended up coming true. Sources from science fiction should count, too.
