Automation and transhumanism are not the problem. The current system of capitalism is the problem. Automation is going to destroy that system and that's why some people fear it.
In the tong term, the percentage of the population that works has been declining over time. In the UK, before the industrial revolution, over 75% of the population worked but now just under 50% of the population work. Those who claim the industrial revolution didn't cause job losses are flat out wrong. They're talking about absolute numbers rather than relative ones.
The population is increasing at a faster rate than jobs are being creating and therefore, there are less jobs opportunities for the population. This is because technological progress increases productivity which allows less people to do more work. At the same time though, that increased productivity increase the generation of wealth which in turn allows people to be removed from the labour force, for example children and pensioners. This is why it seems like automation hasn't led to job losses in the past - large parts of the population have been removed from the workforce. This is why we have 5% unemployment figures instead of 30%.
Society adapted to the automation of the industrial revolution by redistributing more wealth and will do so again by increasing wealth redistribution in the form of UBI.
UBI will only be a short stop gap measure though to get us through the transition. That transition is not to an automated society though, it's to a virtual society. Automation is just a small part of it.
The real fun starts with brain computer interfaces (BCI) that can read from and write to the brain directly; providing completely realistic and fully immersive VR environments. With this technology, any experience you could have in physical reality could be had in virtual reality as well.
People will want to spend all their time in VRs but will have to come out to maintain their bodies. The market will provide those people with life support systems. Why bother maintaining the entire body though if only the brain need to be maintained? So, what we'll see, is people discarding their bodies to place their brains in maintenance tanks that incorporate BCIs, vastly reducing the amount of space and resources they consume.
The next step down the path of progress come from converting our biological brains into synthetic ones that can be maintained from using electricity alone. With that step, we become immortal minds that can live in any environment as long as we have suitable shielding and power. Given the greatest source of power in a solar system is its star, the logical thing fro these synths to do. is to build Matrioshka brains around the stars.
This transition may be scary to some people but it's going to make life far greater than anyone is even capable of imagining.
