Ok. That wasn't all that obvious not all that long ago.
> But machines can't decide what to weld. For now in that arena, things are mostly still human controlled.
Yes.
> I think your argument gets significantly weaker when you push truck, car, and plane driving onto the conversation stack.
What's so incredibly special about truck, car or plane driving/piloting that you feel they are immune to automation?
> Even the best of self-driving AI automation isn't nearly as good as bad human driving. Yet.
Precisely. Let's give it 10 years and look again. I wouldn't bet against it.
> But the absolute best human weld joints are no better than the absolute best robotic weld joints.
It's not about 'best'. It is all about repeat accuracy and consistency. That's what makes the robot better. Maybe the best human welds are better than the best robot welds. But to get a human to consistently outperform the robot or to consistently deliver a specific quality level is not going to happen.
> I think you're talking about two entirely different domains here when you conflate welders and couriers.
We consider welding to be a highly skilled job and yet welding robots are a thing. Courier on the other hand 'merely' requires a driving license, something we hand out to 16 year olds after a perfunctory inspection.
> One of those needs a human decision to place the components to be welded next it in front of a robot that basically does one thing.
Which takes a couple of years training for a human.
> The other is an actual adaptive AI that's trying to make decisions on it's own.
Yes, it's a harder problem for a computer. But it was mostly harder because in the past computers could not see the way we can. But deeply layered convolutional neural networks and their descendants have changed that, dramatically. What was SF 5 years ago is now commonplace. And computers now have access to senses that we don't have, such as radar and lidar.
That takes care of one of the harder parts of the problem.
There is still plenty left, but one of the most formidable obstacles to self driving vehicles is now behind us.
> Yes, it's obvious that the lowest-wage and lowest-skilled workers are going to be displaced by robots the soonest. That's like arguing that the sun is going to rise. And as a society, we need to account for that.
Yes. But I wonder if we're going to be ready when the software is ready. In fact I doubt we will be ready. It will be the industrial revolution all over again, only this time it will play out in a decade instead of in 100 years.
> But arguing that the lowest hanging fruit of automation is going to displace taxi drivers and gardeners in the next 10 years is pretty nuts, even for HN.
I don't think that was called for, that's pretty rude, even for HN.
