There was once my digital integrated circuits professor went to tour at a renowned Car Factory in Germany.
Salesperson : Our cars have equipments powered by FPGA circuits to provide functionality to its users.
Professor : Then, I will not buy your cars.
Salesperson : Why?

Salesperson : . . .
wikipedia: fpga , alpha particle
I like my digital IC class, but my professor gave me an A- :(
