There will always be further technological advances , but judging from historical patterns , the old ways often continue to coexist alongside the new .
We have modern firearms , but still have black powder and archery hunters , cowboy 3 gun shooting events etc .
My wife loves her advanced electric toothbrush . I much prefer a manual .
My father was an early adopter of the electric carving knife and proud of it . I've never owned one and don't plan to .
I don't think our familiar type knives will be entirely replaced anytime soon . Simple , useful and relatively inexpensive .
