The point of ModeS and Datalink was for this, communication-less ATC.
That's where many of the mistakes occur, readback/hearback errors. First
heard about this at least 10 years ago. But the idea was a display/printout
of a clearance, not having that clearance go directly into the GPS/FMS.
Do we really want that? Maybe after accepting it, then pasting it over into
your flight plan.

The FAA had big plans for ATC communications datalinks dating back to the late
1960s.~
