Indeed @sean-king, technology advances exponentially, and a common example of this is the processing power of computers (they get more powerful as well as decreasing in size) or the graphics in video games.

There is concept called technological singularity that consists on a hypothetical event that might happen in the future if we continue with technology advancing exponentially, have you heard about it?

Another factor to take into account, is the implications of AI advancing exponentially in their knowledge and skills, that is why Elon Musk is worried about that specific technology.

But either way, I think our future is going to be better than our present, just like our present is better than our past.
