The healthcare industry would hate it unless they find a spin on it. I hope he gets high profile backing to keep it from being killed. Can you imagine what would happen if they had a few of these at homeless shelters? When the indigent show up at hospitals with proof of a life threatening condition, even if it is in the very early stages, they cannot be turned away. It's likely the government would have to step in and bail out hospitals to keep them and a big chunk of the middle class from going bankrupt. Charges for people who can pay would skyrocket to cover the costs, which is what would threaten a lot of people with bankruptcy. I don't see a way out of that hole other than single payer. Yeah, I would call that a disruption.

Check out HiLetgo on Amazon:

The only thing missing is the Sparkfun logo. That and they don't solder the ADDR high or low. Also I tried them without cutting the pull up traces on either one (supposed to if you gang the I2C bus) and they worked fine. All the instructions and code at Sparkfun worked fine. The only reason they died is because I plugged a cable into the wrong 3 pin connector on the galvo controller board.

I met with the guy whose project this is today. He has another person who is more hardware oriented that is going to do the real card on a PCB. It will be controlling some other parameters as well. So I will be writing for the Arduino (what the hardware guy is using, building a shield) and a PC side interface to interface with it. Or probably I will - he wants a job price so we have to hammer out details and agree to a number. This is his company:

Very bright guy. Take a look at this:
http://i-diagnostics.net/

That's a pretty amazing piece of tech and he isn't trying to make money. He wants to get grants/donations to make it non profit and get it in use everywhere. It says cell phone camera, but due to dropping costs he is looking at a CMOS camera and OLED screen built in to the unit instead. He jumps into the self eradication a little quickly on that page. His fear is that genetic manipulation is becoming more widespread and easier to do every day and that someone will make a biological weapon that will wipe out nearly everyone. Early self detection would be one of the few ways to stop the spread. Anyway, I saw one of these units today; it really exists. He had a cartridge that looks for early markers of heart disease; some kind of protein.

I am a believer in basic income.

and of course the recently trending Rutger Bregman:

The linked video from the article is pretty good. If you are against basic income, you don't want to debate him.

Funny you mention the 4725. I was going to do that with the Arduino. Made a wiring mistake and smoked them. Only briefly touched 15v. But I had them working; sending commands to the Arduino and measuring the voltage out and it was fine; I would have more range at much higher resolution if I do that again. It was a pain to wire on a tiny breadboard. It's only a little more in parts to get the full -5 and +5 for full range, but if it isn't needed why bother? That axiom may hold true for the DACs also - if 3.3v is adequate, why bother with 5? The level just pushes other logic. There is a standard for galvos that specifies a hardware interface using +5 and -5, but the controllers/motors actually use +15/-15. It may be useful to have BT and WiFi. OTOH, if this gets done in bulk, a MCP4822 on a PCB will probably be the way to go. A single cheap chip will do both channels.

All that fancy hardware baked in - WiFi, BT, dual processing, etc...

I am using it to take some simple commands to drive the DACs move a couple of galvos only a short distance. The galvos take +5 and -5 and I grounded the -5 inputs and just drive the +5, but only up to 3.3v. The guy I am doing it for develops commercial microscopes and this is to point a laser around for some kind of spectral processing. It doesn't have to move the mirrors far at all. And he actually has money - a part time gig that pays. Anyway, I will probably get 12 bit 5v DACs mounted on a PCB for a little more range and precision if he moves forward with it. Seems likely since the prototype can do what he was hoping. He picked up some cheap imported galvos and driving them with a microcontroller the cost of it compared to the higher end stuff is amazingly cheap. Seems to have pretty good accuracy and stability.

^^^ I think even lot of skilled blue collar jobs that don't require a degree are not going away, or at least not anytime soon.  For all the reasons you described about robots, they are not going to take over carpentry, they are not going to weld bridges, or be electricians, or plumbers, etc.  If fact there is a huge shortage of people getting into these professions and that's causing serious issues of it's own.  There is WAY too much emphasis on the idea that everyone needs to go to college and that's simply not the case.

I agree with the latter part of your statement completely. One of my kids is not so sure about college and I would be more than okay with him going into a skilled trade. In 18 months he could be an AC tech instead of working at Dunkin. I learned to program at a tech school and have had a 40 year career (so far) earning as much or more than my college educated peers.

As far as your first statement, I think that assistive tech will reduce the number of workers needed in a lot of cases. It would be quite an undertaking to make robots that could work together to build a house, but what about one that just frames out windows and doors? Or laying shingles in big open areas of a roof with a human inspecting and doing the advanced stuff around chimneys and standpipes?

I think you are on to something with the protest notion. I think if Bernie had run as the DEM candidate instead of Hillary he would have won. Not because most people are that far left (I am, but recognize that most are not). Not because of Benghazi or the email saga. I think he would have gotten a big chunk of the protest voters who wanted to throw a brick though the window of ineffective government. A lot of Trump voters were voting against business as usual.

On a separate topic, I think some of the authoritarian crap Trump is trying now is because he is backed into a corner. He is fighting too hard to keep his taxes from being scrutinized, to keep security approval records from being subpoenaed and pushing back too hard on any sort of investigation claiming he has been exonerated when he clearly has not. He is in real danger and despite all his bluster I think he knows it.

For pain management, as you intimated RTG, opioids could be a complete disaster.

But modern opioids still have their place, are very effective in anesthesia where the patient is put out and brought back relatively quickly and the patient is not left with the memory imprint of the intense euphoria.  This was made possible in the 60's with a very fast acting synthetic opioid (fentanyl), that is 40-50 times more powerful than Heroin.

The irony is that the current opioid crisis in the US is fueled by the influx of pharmaceutical grade fentanyl, which is smuggled into the US from China through Mexico and and to a much lesser degree, Canada.  You can't lab your own fentanyl here in the US for the cost of ready made product, that's how inexpensive it is...

"the memory imprint of the intense euphoria" - that's a good technical description of "a fleeting glimpse, out of the corner of my eye". Some people shrug it off and some of us go "Holy shit!" and while I was never the best behaved child in class, I don't think it is purely flawed character that pulled me in (though it likely contributed).

On previous surgeries, I enjoyed the opioids a little overmuch, so after my recent one (shoulder scope), I didn't get them. It really wasn't that bad. Yes, I think the drug industry is convincing us that we should never have to deal with anything there if there is a pill to make it more comfortable. And while I take responsibility for my issues with the painkillers, I have had experience with lots of other things over the course of many years and nothing else had that kind of pull. I was able to pull out of the dive but I completely understand why not everyone does. Opioids should be a last resort for severe pain and patients should be closely monitored, IMO. But they were giving them out like candy.

"was it her plan or was it all part of the script" - I am not sure I have ever seen a more blatant false dichotomy.

Why would you say that?

Because it reads like the only two answers are the same answer.

https://www.nydailynews.com/news/national/ny-canada-death-medical-costs-family-father-quebec-vacation-florida-20190409-a4gzyas42vceppqudl33fgtt3y-story.html

It’s wrong that this family needed to go through this. 
What medical costs would they have incurred post-mortem?  Assuming there would be no autopsy, wouldn’t they have had to pay just for transport back to Quebec?  That wouldn’t be cheap, I imagine.
Probably transport to the hospital for an autopsy and/or certification of death. I wouldn't jump to the assumption of no autopsy. There are legitimate reasons for wanting to examine someone who died here after recently having been abroad, though a vacationing Canadian is highly unlikely to have some dread disease.

Kim has played Trump like a fiddle. As it was obvious he would: Kim is smarter.

But it is - probably - better that the US and North Korea are talking. Assuming it goes somewhere. Otherwise Trump has legitimised a very unpleasant tyrant. Or perhaps I should say *another* very unpleasant tyrant.

He is also making overtures to Sudan.

What I am saying is that there are racists in our country, and they do belong almost entirely to one party. 

Almost entirely huh...? ;D

There are NIMBY (Not In My Back Yard) liberals who publicly support equality but don't practice it personally. They think everyone is entitled to equal opportunities but that not everyone should be required to provide them. I am am not sure whether to call them racist or not. If you think they are racist then I will have to amend my earlier statement when I said that all the racists I know support Trump and just say that the vast majority do.

Not all Trump supporters are racist, BUT every racist I know strongly supports Trump

Same. I was born in AL, raised in GA (still visiting AL relatives frequently) and now live in NC. The sample size for my anecdata for this observation is embarrassingly large.

That’s just opinion, do you have anything else?
Actually, you can quite easily read through this thread (and related ones, if you wish) and count up the number of vile posts, then determine the political affiliations of the authors, and then you will see this is fact, not opinion.

While it is not the case that all right wing posters on this forum write unpleasant and yobbish posts, it does seem that most of not all of those posts that meet that criterion are by written Trump supporters. However it is important to observe that “all tomatoes are red, but not all red things are tomatoes” as regards this situation: In other words this is not an observation aimed at all of those here who hold right wing views, only a subsection of them. However I would expect those who are right wing but not also yobbish to recognise that the current White House encumbant has attracted a certain element, and his particular style of discourse has perhaps emboldened that kind of behaviour. That seems to show itself on this forum. And *that* is an opinion, not a fact.

In my earlier post, I wasn't just referring to this forum and not to just a single poster. This seems to be pretty widespread. I agree with your opinion about why. Trump is saying things like "sick people"and "pencil neck" and hurling a host of other insults when talking about members of congress, judges and even members of his own administration. I also agree not all posters who are right of center do that.
