Weather "Technology" is improving fast or slow is a matter of perspective. I could point to tons of advances in science, biology, and other technologies, but you could just as easily say the first synthetic life, gene editing of human embryos, the solving of the protein folding problem, or tons of other discoveries, advancements, and life saving treatments, being figured out every single day, are not significant. It's all a matter of perspective.

But as far as self driving cars, and Ai doctors. These have been promised to be 5-10 years away for 70 years. Humans have vastly underestimated the complexity of human intelligence and problem solving, over and over throughout history.

But technology is moving in that direction. More and more powerful super computers, and better and better intelligence algorithms exist every year. It's like a train moving towards it's destination, and when human level AGI is created it will be super-human because computers are already superior in many ways to humans. Self driving cars and ai doctors will be solved along with the automation of nearly every other job in existence.

Ai scientists will be advancing technology and science faster than humans ever could. Shorty after that is when you get self replicators and commercial travel to terraformed mars. That's when technology and resources scale exponentially because intelligence itself is in a feedbackloop of growth.

I can't say when this future will occur, but it is what many call the singularity and it's why so many companies around the world have invested hundreds of billions of dollars into the problem, which has been measurable moving us closer and closer to that goal.
