It has been said that we are out of things to create, the only thing left is to re-create/redisign/improve the things we have now. For example hybrid cars, hydro. fuel cells, carbon fiber bodies with aluminum frames, all in an attempt to recreate the car (to reduce emmissions as well as dependency on fossil fuels). We have been blessed with real-to-real sound recorders, then 4-tracks, then 8-tracks, the cassette tapes, now CD's, as well as mp3 players, and DVD's. Just look at all the stuff that has been done in the last 50 years, who knows what the next 50 will bring. Someone else posted about all the invention and innovation taking place inside large R&D facilities inside major corporations, and it is true but that means we have multiple Einstien's, Edisons, Tesla's, Bell's, Curtiss's, etc. now working together instead of all alone, brainstorming and accomplishing great things we just don't hear about it as much. Anyway, thats my 2 cents worth!
