What are the classification of technology?

Technology is Classified into generations.

First generation tech has limited use and is usually full of bugs and problems.

The second generation is usually exactly like the first, except without the bugs and problems that consumers have reported.

The third generation is put on the market after already establishing customers and a wide knowledge of their product. It's basically the same as the second generation, but with new features and benefits, to intice the consumers that were borderline on the decision to buy the second generation.

The product goes back and forth between putting out new features and fixing the bugs until it no longer can create revenue for the company, and production is ceased.
