I agree. We wont find a cure for cancer and other things if we don't continue to advance in other things. Like this robot bug. Maybe we made a new technology for it that we realize can be used to cure a specific illness. So yeah i agree we can always be continuing other things to improve on more important things.
I agree, but it should also be considered that things like this are being researched to use in actually spying applications. Similar to how those drones are used to hover around buildings in desertland
