"I think my view is that whenever you project into the future you're never likely to be accurate in the details, or the paraphernalia and style"

In this quote, Stephen Fry is sharing his idea that making forecasts regarding the future is not always accurate or trusted, as it is tough to make up all the details and subtleties that may come into play. Furthermore, he recommends that focusing way too much on the superficial facets of the future, such as style or appearance, might be lesser than recognizing broader trends as well as end results.
