We are not discoverring any new laws of physics, string theory has been in the hypothesis stage since the mid 70s and things like DNA and computers are just complex arrangements of existing knowledge.
Has science reached the point where the only thing left to do is invent?
Wow. You fail so horribly it's not even funny. You're the kind of idiot that journalists manufacture.
Science is moving faster now than it ever has before. Biology is probably the fastest moving science right now; more has been learned in the past 20 years than in the past few centuries. The new LHC is opening in CERN next year, and particle physics is going to literally explode. This is the most exciting time to be a scientist, and it clearly shows that you aren't one.
Sage for blatant ignorance and sheer idiocy. Become an hero, kthxbai.
