Ask HN: What is the next industry to be disrupted?

There's a lot of talk about what industry start ups and new technology will disrupt. I usually hear legal and medical, but I haven't seen much head way yet. What do you think the next one will be and why?

Lobster rolls. wait

I'd guess it will be the one most people are trying to disrupt. I know that sounds trivial, but if you throw enough hackers at an industry, something new will probably come out. There seems to be a lot going on in education, and even though it hasn't been totally disrupted, there appears to be enough effort and focus that it will happen eventually.

I received a 3d printer last week, at work. I ordered it to try and make some oilfield equipment models. My expectations in truth were low, the printer is a cheap hobbyist unit (Makerbot Replicator 2). After using it for 2 weeks, I am very impressed. The mechanical properties of the PLA plastic used are much better than expected, and there are things you can make that would not be possible with any other manufacturing process - eg. objects with an internal 3d honeycomb structure for great strength and lightness.

I think the technology can already disrupt such industries as hardware shops, spare parts warehouses, hobby shops and of course industrial model making. In the future I expect 3d printed concrete buildings, and mainstream consumer goods.

Academic journals. It is not hard to host PDFs, I mean look at arxiv.org/.
