What is the best technology ever?

fire and paper PAPER Paper, yes paper, is still the best, least expensive, most long-lived and most reliable technology: - It doesn't need to be upgraded. Paper has not significantly changed for thousands of years. A hundred-year-old piece of paper is still usable -- readable and writable -- today. - It does not need electricity or any other power source to function. - It does not crash. Unless you spill something on it, or take the effort to light it on fire, you will not lose your work. - Industry standards are open and widely accepted. Paper comes in standard formats for standard purposes: Letter-size, tabloid-size, index cards, business cards, etc. These standard sizes fit standard devices such as printers, fax machines, etc. - It is ligher in weight and more transportable than any other technology. - It's inexpensive. The entry-level price point is just a few cents. Usually it can be found for free. - It's easily learned and used. Just about anyone in the world can be up and running in minutes, even a small child. But many people dont consider fire as a technology

What seems to be the best of today may become very old tomorrow.Therefore we can't permanently fix a particular technology as a best one. It is changing and improving day by day!
