This is similar to complaining that we don't all have the opportunity to spend 8 hours a day doing backbreaking farm labour after the agricultural revolution - it is only important to have people labouring if the labour is achieving something useful.

Labouring for the sake of doing labour is stupid. If robots can do it cost effectively, they should.

Same can be said for every country right now. And now, there's fewer and fewer reliable greener pastures that unsatisfied people can go to, which used to let off some much needed steam.

The people will always have something to do. What those somethings are is entirely up to the ruling class.

China has an aging population like most countries. So, automation will likely help fill the gap rather than make work obsolete. However, if China does get to the point where a lot of work is automated, they have a socialist system where the government can do things like step in to reduce working hours or provide universal basic services which would be impossible in the west.

Ultimately, the whole point of an economy is to direct labour and resources in a way which allows people to have a good standard of living. If most labor can really be automated, then people can just spend more of their time enjoying their lives instead of working. The technology itself is not the problem. The only reason this becomes a crisis under capitalism is because the means of production are privately owned, and the people who own them require the rest of the population to sell their labor in order to live. Automation under private ownership frees people from a paycheck, while the owners keep the gains.
