Looking at long term trends, the only single thing I can be sure of is the future won't look like the present.

I am currently experiencing a strong drive to start a family. Lets say I get very lucky and cause a pregnancy tomorrow; kid comes out 9 months later, 21 years (± whatever for when school starts), they graduate university and… it's not predictable in the slightest. We might have single-atom transistors as standard, or the factories might be too expensive to mass produce them. We might have solved all genetic conditions, or research might have stalled with Moore's Law. AI might be good enough to make human labour uneconomical, which is a separate issue to if we will arrange our economies to make this a utopia or a dystopia, or it might not. Even without AI, internet connectivity and robotics is enough to make Amazon Mechanical Turk more like its namesake, with the same impact on cost-cutting and outsourcing to whoever has an internet connection. Genetics research, even if limited to no-growth-in-computing scenarios, may also make it affordable for small and dumb terrorist groups to attempt DIY genocides, and even if they fail at their goal that may still cause megadeaths… but we may well also have defences against it, either biological or surveillance. Similar issues for drones and high-powered lasers. We've already got government-affordable ways to put literally every human on the planet under 24/7 surveillance, and that's likely to get cheap enough for organised crime to automate blackmail, but we also already have people doing that with generative AI and the social responses (let alone the legislative) could be almost anything. 3D printed houses and boats are both realities now, will we finally witness large-scale seasteading, or is that fundamentally untenable?

And that's all assuming no world-ending, or even just economy-ending, catastrophes of any kind — no paperclip optimisers, no nuclear wars, no peak-${insert-resource-here}, no environmental issues causing 1e9-scale migration.
