Is The Rate Of Technology Breakthroughs Slowing Down?

Still no new viable energy sources? Nuclear power and coal is still the most effective and low costs power source.

The 100+ year old combustion engine is still the most effective and still running fossil fuel.

The computer is still based on transistors either being on or off, just like the vacuum tubes of the 40's, only faster and smaller.

Lack of ability and economic power to send humans into space.

Lack of breakthroughs in how to effectively treat common diseases.


What else is not happening for the human race at the moment?
