Any forecast of what is to come is shaped by the anxieties, desires, and assumptions of the moment it is made, making it a better mirror of the predictor's present than a window onto actual coming events. To read old predictions is therefore to study the psychology of the era that produced them.
The three tenses carry radically different epistemic weight: the past is fixed and knowable, the present is fleeting, and the future is fundamentally unknowable. This asymmetry means our confidence should scale inversely with how far forward we project.
Rumsfeld predicted the Iraq war would last six days to six months, while Eisenhower and McNamara forecast inevitable victory in Vietnam years before defeat. Authority and access to information do not immunize experts against catastrophically wrong predictions delivered with total confidence.

Genuine innovation demands the invention of new instruments and approaches, not the refinement of familiar ones.
