Ever flown in a plane ?

Can you imagine how foreign to humans the concept of flying machines were when they were invented ?

How many people would have died in plane crashes in the last 100 years ?

And yet they continued to get developed to the vast benefit of mankind .

Sure , someone made some money out of building aircraft . But they only made money because there was demand for the product .

Same as autonomous cars .
