I would love to see future technology come to The Sims 4.
I wasn't into the time travel part of it, but I did have a blast with the expansion.

I had my sims own a plumbot making business.
They started out as suppliers to the plumbot emporium by making components in their basement.

They later bought out the emporium and started making the plumbots as well.
They also sold other future technology from buy mode objects.


I also combined the EP with University to build a high tech dorm.
My uni students worked on their technology skills while living in the dorm.
It was awesome.
They should use some other method to introduce advanced technology to the sim world.
Like perhaps a mysterious abandoned alien mothership appears in orbit and your sims get to explore it to unlock all of its secrets.
They could invent new objects from researching alien technology.
