Scientific progress.

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?

Wild theories are typically greatly ridiculed even if they make sense and then there's some areas scientist refuse to delve in. Such as in archeology we got lots of interesting unexcavated areas, but no-one's willing to explore them. There's also some technology we have forgotten, but sadly no-one wants to develop them further even though they do have potential. I feel that this is harmful to research and innovation. It wasn't like this in beginning, but I guess it's just that scientific community has become old and senile.
