Many many year ago I started in the computer industry, it seemed like every day a new company would startup.

Many of these new company's never made it past the first couple of years, leaving a grave yard of computer companies in the wake.
This is the way the industry went, this is also going to be true for many new industries here today gone tomorrow.

Get use to this because I do not believe it will ever change.
We have too many people with startup company's not enough buyers some will never make the cut an only the best will survive.
My 3D Printer is 3 years old an already obsolete, the company has rebranded still making 3D Printers but not any of the 1st - 4th generations.
