So from a forecasting standpoint: our short term predictions tend to overstate progress. But long term our predictions tend to understate progress.
I would tend to agree with Aaron on this one. You can clearly see from mid-age posters that a lot of over-optimistic predictions failed to materialize

but they would have materialized in case fission became the source of plentiful, cheap and safe power, but it did not.
