Will Ethereum txs be private by default in the future?

Currently all transactions that happen in Ethereum Layer 1 are public, and the balance of each address can be seen. There are some tools to make transactions private out there, but I was wondering if Ethereum plans to make txs private by default in the future.

I remember I read something about this but can't find the link. Does Ethereum community or core devs value this privacy? Or they plan to have it always public and only allow private tx in rollups?

Thanks
