craig venters says, well, what we're going to do is we're going to ensure there is, you know, intelligence in the machines that goes and does lookup, you know, sequence comes in, walk around the sequence, looks it up on the interpret, and it needs to, sort of, pass the test of not being dangerous, and only then does it print. buy a photocopier, there's intelligence this there to look for u.s. dollar, and i never tried to take a copy of the dollar bill, but it's supposed to detect currency and not let you do it or put a water mark on it. there's presence to suggest you can put technology in the machines to check bad stuff doesn't happen. if it's foolproof, probably not? could it be hacked? probably. that's craig's best answer to the question. >> you're sleeping find over these issues? >> you know, i -- i'm -- i'm, you know, i'm an optimist. b, i think we can never anticipate these things ahead of time. look, when i was a kid -- not a kiddings u -- kidding, but growing up, test tube babies were out there. remember test tube babies? the 7 os; right? >> uh-huh. >> i thought they were going to

i had a privilege to talk to craig venter, this biologist in new york who is developing a printer -- we know how to sequence genes supereasily, gene sequences are not hard, you can find the mont ebay but dna synthesis, we know how to read the dna and print the dna, that is dna synthesis, a big industrial tool, desktop size, every year we all get our flu shots, guess what the flu is going to be this year? we never know. it propagates from asia. rather than guessing at the beginning of the season, the doctor sends you an e-mail saying turns out the fluid is this, here is a rococo, print out your own vaccine and get a little liquid and drink it, that is a 3d printer as well, printing dna which is a physical material. obviously at this point you have to have questions of what could go wrong, ideas like -- a little too littoral. this you won't print and iphone soon, if and electronics at various stores and semiconductors. it is pretty bullish on this. i think will happen fast and the only thing -- the only caveat i would make it is not mass production technology. the prototype technology,
