So like in say 1000 years the world will still be the same?

It'll crash one day. The world will change. Statistically speaking when it does it will likely be for the worse too.

You're currently right, but the world is changing

Sounds like recency bias. Every historically dominant fiat currency has eventually lost its dominance.

It doesn’t have to crash per se. The value can go down. As in inflation. This is already happening in some sense. It’s just accelerated when the real value you get back is lesser for dollar by the day. A few years back can you imagine buying a $1000 phone? The measured inflation is really convoluted. I doubt it measures the true value of a dollar. The good thing is other currencies will just get devalued equally considering dollar is the world currency for the most part.

People routinely spent over $1,000 on computers, cameras, video cameras, etc and a phone does all of those things well.

You can read about how inflation is calculated, it makes sense: https://www.bls.gov/cpi/questions-and-answers.htm
