Thats because there's some shocking pretend plumbers amongst us.
I'm comparing with the ones who turn/turned up at jobs, to quote. I need/ed quite a few for renters & flippers.
I don't know how to phrase it, I won't say "average" but there's a large proportion of people who call themselves plumbers, who aren't competent despite what it says on the van.
Your on you own. You haven't prepared. You books wont have the answer.
No you tube video or Ai bot could tell you how to go about what's in front of you.
Or give you a product knowledge that will not only fix the problem, and give you confidence in walking away and being able to sleep soundly that night.
That's what I expected so I took some measures as mentioned. You haven't prepared to answer - you didn't read!! FAIL!!
Of course those who can only do plumbing, will tell you that you need years of experience because they have to defend themselves. They wildly overstate it. I know enough to know. Of course it's a subject where you never stop learning, but the process is vastly accellerated by better mental processing power. Where AI is concerned, it will have all of your experience, all of mine, plus some humungous number of other plumbers, plus it can work things out for itself better than any. It has the resources of every plumber there's ever been. It will see what's in front of it and deal with it. Frightening , isn't it.
It's really easy to think humans are special, as though "life" means something magic. Or "intuition" - you can go on - to "soul" or "sprituality".
There is to date no evidence whatsoever that these things are the products of a spooky biological mind and can not be that of a human-assembled one.
As a thought experiment, consider that a component of the brain, by itself, is understood. It might be a switch, ir a distribution point, or a physical association of interconnected neurons to make a memory (an engram) which gets tagged with a timer cell.
We can make those, - or, we can make things which behave in exactly the same way. It's not all sussed out, but everything found that's new, is still just a difference in connections. So we can in principle make a whole brain. Spookiness is still there, if you have all the connections right. Is it?
That's an oversimple way of looking at it.
What AI does is work stuff out for itself. We know that the layered idea model it uses, is close to how the brain works, because the outcomes match so well. WHat we don't know all about yet, is what the side effects might be. LIke, if AI was given the rough idea of a motorbike and told to make one, it could get on with it. But it wouldn't sound the same. You can't take a bike apart to find the noise, it's not poart of the spec. So the AI one is gonna sound different. Humans, especially the predictable ones, will inevitably take that as a sign that the AI got it wrong.
