Re: There is no point arguing with closed minds, ignoramuses or bad losers.
1. I'm already on the record about debunking the extent of the 3D claims:
2. I did say it would take 50+ years to mature into being practical proposition (as most technologies do--want more examples?)
3. 50 years aren't long. The issues I'm talking about will be centre-stage well before then as this technology is screaming ahead ==> read 3D printing as an inseparable subset of nano technology (i.e.: all that nanotechnology entails).
4. Before you lost sight of what I was about, I was referring to bureaucrats being spooked--not me! The fact is bureaucrats are already spooked. You don't have to be Einstein to figure out bureaucrats will be spooked when you mention illegal weapons, terrorists, illegal drugs, copyright and patent violation in one sentence--or one paragraph for that matter. And thus it's clear to me that it won't be long before draconian regs appear.
5. I never mentioned DNA, you did. But seeing you have:
...And whilst reading this remember my skepticism and what I said about 50+ years.
6. I did add ...etc., etc., etc. There are any number of similar references in the scientific press if you are prepared search (as it seems the bureaucrats are so doing and succeeding). You could begin with that rag New Scientist which had an article on the subject a short while ago. There are any number of other articles in more learned rags, Nature and Science for instance (I don't have my copies to hand for the refs as they're at work but I'm sure you'll find them online if you look).
7. Back to basics - the concern I'm expressing is that the rampant sensationalism 3D-p is causing (such as this video) will thwart the technology--or more precisely that over regulation in response to emotional gut reaction will lock it up in environments where it can be controlled--i.e.: in proprietary labs of large companies away from the hoi polloi.
8. Keep at it. Clearly you're on course for Gold.
