We all know people who need filters. They need to have one last check of what they are going to say before it comes out. They may say things that are inappropriate to the situation or provide unnecessarily graphic descriptions of bathroom habits. Sometimes they reveal aspects of their personalities that should have remained deeply closeted. Just think of the number of times you have said to yourself, “I’m so glad someone invented the term ‘TMI’ because this is the exact occasion to use it.”
In the absence of a filter that works proactively to prevent those little over-shares from coming out, I would like to suggest a retroactive filter for listeners. Once activated, the filter would allow you to make decisions about what you want to hear, or more importantly, what you don’t want to hear. Set to “Get to the point,” the filter would eliminate your rambley friend’s long-winded soliloquies. The “G-rated” setting would remove your co-worker’s potty-mouthed rants. You could set it to “Agnostic/Atheist” for Jehovah’s Witnesses.
I’m envisioning an external device, something like the ear trumpet pictured (because that would be kind of cool), but I’m sure the smart people at Apple can design some kind of sleek looking iFilter.
