I began my work at a time when invisibility was not fashionable at all.
It’s difficult to find anybody in the know who expects there will ever be a device that hides itself and its contents at all wavelengths - if you can’t see it in visible light, then perhaps radar, infrared, ultraviolet or X-rays would reveal it. But optimism for practical uses is growing.
And there’s an issue I don’t recall being acknowledged in Star Trek.
If a cloak were to make an object fully invisible to the outside world, then the outside world would be invisible to the object within the cloak. A thing (or person) inside a perfect cloak is not only invisible. It is blind.
