The hypotheses may have to await technology for testability, but they are both clearly testable.

This seems to be equivalent to untestable. There's no indication that the technology will become available (nor indication that it will not.)

Perhaps. But it's not unusual in the Sciences for an experiment to be conceived of well in advance of the technological availability allowing execution.
