I would say it will be maintaining a balance between artificial intellect (robots) and humans as well as keeping the environment on the go.
Even now, with all these hi tech technologies we are entering a whole new era where human beings are being replaced by machines. What scares me the most is how easy we can be replaced by random machines. What's more, there is no need in so many of us if machines can do it all. By the looks of it, it's just the beginning..
Also, let's not forget about the environment which is suffering from emissions every single day. It's suffered a lot for the past 100 years so it's definitely needs some collective recovery and a boost to a new path.
Of course, it won't be easy but it's something that needs to be accomplished in order to have a future.

Covid is costing the World billions. The next generation will be in debt for decades to come, and the younger generation will have to pay it all back. That means higher taxes, austerity, fewer public services, fewer jobs, higher unemployment, fewer opprtunities, higher pension ages etc. Young people think that Covid doesn't affect them, but they have never been more wrong, and they're going to be paying for it for the rest of their lives. Stay away from anyone outside your household, wear your mask whenever that can't be avoided, and get vaccinated when it is offered to you. Their/your future depends on it.
