It is possible that the current tech used in robotics will somehow form the basis for the work over the next 1000 years or so, either directly or via some tangential discovery by researchers working with current tech.

Without the benefit of hindsight it is impossible to tell with certainty what techs are worthwhile exploring and what should simply be discarded, the idea of discarding is of course based on the false assumption that techs that are later unused never had a use (e.g. we may solve a software problem with current tech that will form the basis for future robotics software).
