Design is no longer as difficult as before. In the past, we were preparing a piece required for design after long efforts in turning or molding. Now we can easily prepare it with our 3d printer. We have advanced programs and we can simulate our design. We can even make the working mini model of the design.

Think that computers that can build computers that are thinking are invented. And add your imagination to it. That's all...

Electricity is slightly different from other professions. For example civil engineering works with meters and kilograms. Mechanical engineering works with millimeters and sometimes micrometers. We try to understand the lightning pulse that happens in a millionth of a second in microseconds. Electricity travels the world 4 times in 1 second. The systems we designed affect the real world but are far from the reality.

Now "TESLA-Elon MUSK" works for mars and space travel. I'm sure they will succeed. What they have accomplished ,will be to make the very difficult space travel simpler.

Nowadays, designs are no longer to invent something new. To further improve existing.
