Arcane and obsolete

Arcane is an adjective that describes someone or something as being less known or hard to understand except for a few people. Arcane things are hidden or secretive. Obscure is another good synonym. This is not always a good thing.

The adverb form is arcanely.

Obsolete is an adjective that describes something or someone as being out of use because of a new version or more popular item. It can also mean something that is not current or old-fashioned.

The adverb form is obsoletely, though this is seen more often as a misspelling for absolutely than anything else. And the noun form is either obsoleteness or obsoletism.

We are conditioned by our contexts, consuming yet complaining; discarding gadgets claiming technological obsoleteness; buying what we can live without; criticising the current affairs knowing well how we are a party to it and publicly grumbling without private initiatives. [The Hindu]
