What will certainly be the case in the year 3000 is that people won’t have to work as much anymore. Technological progress and artificial intelligence will make many activities unnecessary. Whether that is a blessing or a curse, we’ll leave that open for now; the future will tell.
That opens up room for different thought experiments. In one model, people will fight over the work that still exists and possibly even wage wars. You could certainly imagine them doing that.
My other model looks like this: people will learn and become wiser, and therefore stop bashing each other’s heads in and use their wealth of time more sensibly. I’m optimistic and expect this model to happen.
When you have a lot of time, you can devote yourself to the beautiful things in life. For example, you can celebrate parties and dress up for them. For that, I suggest a knitted bracelet :-)
Here’s the pattern.

P.S.: That was a lot of blah-blah for such a little bracelet, wasn’t it?
