Smart Fabrics: Fad or Future?

Fad.

Neither... I don't think anyone is interested despite the endless futile attempts at wearable this and wearable that since the 60s 50s whatever.

It might have begun prior to the 50s or 60s unless you mean the 1650's or 1560's. I am of course referring to the still moderately popular and decidedly wearable watches of both the pocket and wrist variety.

There are also wearable moderately popular wearable audio equipment, hitting mainstream a couple decades ago with the Walkman and in more recent history the Ipod.

The attempts do seem endless, but they aren't necessarily futile. Instances of acceptance are few and far between, but do occur. Some even last centuries.
