- How likely are they to know the work of Bill Gates, Steve Jobs or Elon Musk? Who will be most important to them?
- Will they be most impressed by the fact that we put a helicopter on Mars or the invention of smartphones? Which will be most important in their time?
- Will the tech companies of our generation be remembered and viewed negatively in the same light as monopolies like Standard Oil or colonizing entities like the Dutch East Company? Will the companies of our time be remembered at all?
If I have to make a wild guess what will be remembered in 1,000 years, I would guess that SI units with its derived units will still be in place. [2] These (derived) units are named after some inventors, James Watt, Gustav Hertz, Isaac Newton, Nikola Tesla, Lord Kelvin. Maybe some of them will be remembered in 1,000 years. But keep in mind, 1,000 years is a very very long time. A lot can be forgotten in that time span.

They will remember Einstein and Newton and Aristotle, just like we do.
Most people will recognise the name Julius Caesar but few could say much more (at school I had to read his Invasion of Britain in latin so I know a little - utterly failed the subject)
Ask someone about Aristotle and 99% will have no clue. A Greek maybe.
I would say that outside of people associated with a religion, only names will sometimes live on.
I think there is actually quite a good chance he is remembered in 1000 years. At least in a vauge recognize the name from textbooks kind of way.
