will.i.am talked to Dezeen in an interview to promote his new range of eco-friendly lifestyle items (the slogan is "waste is only waste if you waste it.")
In the interview, will.i.am expressed his concern that 3D printers could be used to print out actual human beings.
"I'm not saying I agree with it," he said. "I'm just saying what's fact based on plausible growth in technology."
will.i.am expanded on his concerns about 3D printing, remarking "Moses comes down with the 10 commandments and says 'Thou shalt not...'. He didn't say shit about 3D printing."
