We've already had massive automation events, the computer, the internet, mobile, self-checkout, etc. Everytime these steps made life better mostly, and more automated or at least allowed most people to be more independent.

The last mile of automation is costly, where the first ones were money savers.

Building physical robots and tuning them, maintenance, cleaning, updates, security, new versions etc etc.

This last phase of robots, drones and self-driving vehicles will take a long time to get right and it is much more costly to enter it. The speed of innovation also makes it quickly out of date when you do commit to it.

The automation remaining involves mostly hardware which is more costly, the initial ones were software that saved lots of money and wasted time.
