Is the Garbage man Dilberts future self?

In Dilberts season 1, & 2.

It answers some weird questions.

For example when Dilbert is stuck behind the garbage man in Dilberts driveway, and he declares that he is “in his own way”. That would make sense if Dilbert was actually the garbage man from the future, and he was literally in “his own way?”

Is my conspiracy theory. After all the GruntMaster 9000 was a time machine.
