The time traveling designer...
/Rules of time travel
The job of the time travelling designer is to travel into the future of the product (or one of many possible futures) and then to come back to tell the team in the present what it looks like there.
You must know (and tell the team) how far in the future you have been.
There can be different possible versions of the future.
The further into the future you go the fuzzier your vision is (something to do with degradation of Tachyon particles). Therefore things in the near future should be crisp and in high-definition, things in the far future are abstract and in low-definition.
If visions of the far future are in crisp high-definition then it was probably a dream, NOT time-travel.
The further into the future you go the less time you can spend there.
You cannot go back in time but you can go back to the future.
