It is interesting to think that because technology has accelerated so fast in the past couple of decades, something like bitcoin would have seemed futuristic or impossible in the 1970's and 1980's. That said, it is fairly easy to imagine a world of no Bitcoin if you can remember back 20+ years or more .
There were no bitcoins 20 years before and we could imagine the world without them only before their existence. Since the invention of bitcoins, it's impossible to live without them.
I can't imagine a world without bitcoin. What if someone says, imagine a world without the Internet and you will say that the world without the internet will be the end of the world. We cannot say the same for bitcoins, but those who are using bitcoin, for them it is like a horrible dream to think of a world without bitcoins.
It is an analysis with nice analogies, and I think that it is important to highlight a considerable point here, and that is that technology will always advance, not only in telephones, or audiovisuals, or smart homes or so many things that machines can do, but each Sometimes things like the economy will have its inflection point as it is now with BTC, at the beginning of 2017 when BTC jumped to $20k everyone said that this was the biggest bubble of all time, and when it fell in price more still, but they did not imagine that it would reach almost $70k, and now they will even less imagine that it will reach more than $150k and it is not said by me but by experts who have had great experience on wall street. In this context it is not healthy to imagine a world without BTC.
