bitcoin smartcontract feature I am a noob, so please bear with me.

I'm wondering whether the Bitcoin Core team plans to integrate a smart contract feature evolving the Bitcoin scripting language in a more sophisticated one in the near for far future.

Afaik, the only work currently done is on sidechains. Any clues?
there is no such improvement planned for the protocol, only the expected BIP are listed in  https://github.com/bitcoin/bips/blob/master/README.mediawiki.
but you should understand why in bitcoin only a limited scripting mechanism is used instead a VM with a contract language as for Ethereum (security reasons). the project RSK aims to provide such opportunity through a sidechain, so explore it.
