What separates the Dentist from the bank teller? Clearly ATM's have drastically reduced the need for Bank tellers, yet nobody seems that concerned about it. More generally, I suspect there is always going to be gap’s when as a field gets automated. As the more complex the task the harder it is to automate and less cost effective it is to do. So, it feels like the steady erosion of low end jobs everywhere vs. a sudden loss of a single profession.

We can see this as an increased demand for education / training. But, not everyone is able to keep up and over time ever fewer people are going to be capable of the remaining niches. It's possible that the service industry's are going to continue to absorb the less capable, but that does not help the economy in the long term.

"What separates the Dentist from the bank teller?"

One of them has his or her hand in your mouth and might need to drill, remove, fill or otherwise mess around with your teeth. I think a lot of people would be more comfortable with a human element in all medical interactions, even if robots are eventually as effective.

> even if robots are eventually as effective.

What about when robots become more effective? Drastically more effective?

I would not let a modern day robot work on my teeth, they are too stupid, but I can imagine a day (fairly soon) when this will not be the case, and my gut reaction will start to be the exact opposite: I would not let a human being work on my teeth.

I wouldn't bet against that, but what I was saying was that right now there is a big difference between a human bank teller and a human dentist, and an even bigger difference between an ATM and some future dentist robot. It's just a bad analogy because they are not similar interactions at all.

We already have robotic dentists doing dental work better than a human can. Back in the dark ages of say 1995 if you wanted to get your teeth into better alignment you went to this guy who attached this complex apparatus that would forcefully move the teeth in your mouth and every so often you would go back to this same person to do adjustments and such. Sure, it often hurt, look a long time, looked bad, interfered with proper dental care, and only allowed for fairly simple work, but at least it was expensive.

Now, with automation and 3D imaging technology we can have a specialist specify what to change and let a computer design a series of discrete non-invasive attachments that allow a home users to quickly attach and remove their implant. It's far less painful, takes less time,can far more precisely preform complex work like rotating a tooth, and the only downside is it costs about the same amount as braces. Note: This is an actual company not just BS (http://www.invisalign.com/Pages/default.aspx).

PS: I still occasionally see a teller for complex interactions, but I trust an ATM to be far more accurate for my day to day needs. And there is still plenty of work for orthodontists, but a lot of the simple stuff is simply better handled by a machine.

That's fascinating, thanks. But has this technology reduced the need for orthodontists? Does it mean that orthodontists now need to learn how to program? I think this is just another example of humans using more software.

It's reduced the time an orthodontist spends per patent and allowed non orthodontists to do simple things that used to involve an orthodontist. But, it has also convinced a lot of adults to get dental work. So, in the short term it's fairly neutral, but in the long term we are going to need fewer orthodontists.

As to programming; I don't know a lot about how the software works, but advanced users in front of really complex software like Excel and Photoshop tend to blur the line between a Specialist and Programmer.

We will hit a raw-material crisis which will force us to cap the production of these machines.

If that doesn't happen, Wall-E future or massive human revolt.
