Failed ideas can be repurposed

oftentimes, these come from a lack of understanding (or misunderstanding)
this is why research exists in the first place
while some are taking risks investing into the new research, its concept and ideas can influence upcoming projects
it could also take note on the failures and flaws of the research
case in point:
- Virtual Boy that eventually popularizes virtual reality
- A bad animation can be used for an amateurish character
- A very alien concept can be remixed with a new familiar concept
