Richard Heinberg proposes a startling diagnosis: humanity has reached a fundamental turning point in its economic history. The expansionary trajectory of industrial civilization is colliding with non-negotiable natural limits.
The above article is about Moore's law and diminishing returns on technology. Computers and television have been around since the 40's. Cars, electricity and telephones have been around since before 1900. Space travel and satellites has been around since 1957. Solar energy and windmills have been around for centuries. Most of the major inventions were invented in the 1800's and 1900's. Has much new technology been invented or has it simply been refined over a period of time?
I mention all of this because most people say that technology will save us and that something new will come along. That is quite a gamble. Perhaps its the simplest solution that will work, living within our means.
