By the time I'm proper old I'll be amazed if there's a state pension of any sort.
We haven't even hit peak baby boomer yet. The number of adults who are retired and claiming pension is increasing. Look at this chart for the US, for example:

Look particularly at the 50-64 age ranges which are relatively larger, and the 5-19 age ranges which are relatively smaller. In the next 10-15 years, all those baby boomers will be hitting pensionable age, whilst a lower number of Generation Zs will be taking their place. On top of that Millennials are having less children, and so the trend is only going to get worse, with a growing elderly population and a shrinking workforce.
Inspect that same graphic on the different European countries. Many are hitting an inverse pyramid demographic graphic, so it's basically game over for state pensions, not even minimum pensions will be delivered to millennial by the time they are 65 (or 70... since they keep making us work for longer). So we must have our own set of passive income sources, or else we are pretty much fucked, specially those with physical jobs. If your job is not too taxing on your physique you may stretch retirement for longer, but even then, your mind slows down with age and you cannot put as many hours anymore on mental tasks. People often underrate how many calories mental tasks can burn.
I see Bitcoin as a must have in a 2030 portfolio, what else do you consider? Bonds are out of the question, so which stocks would you hold? Will giants like Coke still be a good pick for some passive income through dividends by then? we must start planning now, 10 years can go by very fast.
