I have argued on this forum in the past that I believe the eventual direction we are headed is towards single pilot with remote backup.
However, what I think is one of the biggest speed bumps to our eventual job losses is simply the fact that the industry hasn't decided what path to take forward. Are we going single pilot with remote backup, or are we going fully remote operating, or are we going to make the huge leap to autonomous control?
In my mind, you can't even begin to discuss a timeline until we know where we are headed.
I am a huge automotive industry buff. I have very closely followed the path towards automation in cars. The one thing that I will point out is there are many baby steps along the way, followed by a single giant leap.
Baby steps have been occurring for a long time. Think, anti lock brakes, traction control, stability control. Then blind spot monitors, radar cruise control, automatic emergency brakes, and lane following. Currently, Teslas can change lanes on their own and even take highway off ramps.
Those are all accomplishments, but they are a long way from hundreds of cars perfectly merging on and off of freeways all by themselves. To have a computer system that is overseeing all traffic flow and controlling all vehicles speeds, and order of flow, is a huge hurdle and still a long long ways off.
My point is that there will be many further baby steps that will occur long before we are kicked to the curb. That being said, I'm still aggressively stashing cash in my 401k
