do mojang delete old contents in minecraft in the future

Mojang Studios, the developer of Minecraft, has historically shown a commitment to maintaining backward compatibility and preserving the game's content for players. They have not typically removed old content from the game, as doing so would risk disrupting players' experiences, especially in terms of custom builds, worlds, and server setups that rely on those elements.

However, there are a few scenarios in which changes to existing content might occur:

1. Updates and Refinements: As new updates are introduced, some mechanics or features might be adjusted to improve balance, performance, or to fit with new game systems. This could involve tweaking older elements rather than outright removal.

2. Technical Necessity: In rare cases, for technical reasons such as fixing major bugs or resolving security issues, certain content might need to be altered or deprecated.

3. Content Overhauls: Sometimes, parts of the game world or specific features undergo redesign to align with new themes or updates, which might result in older content being visually or functionally updated.

4. Community and Feedback: Mojang is known for engaging with its community. If there's significant feedback about certain content being outdated or problematic, they might consider changes.

It's important to note that any large-scale changes like removing content are typically communicated well in advance through official channels, and Mojang tends to provide ample time for players to adapt, especially in scenarios involving server operators or mod creators.

For the most current information regarding future plans for Minecraft's content, it's best to follow official announcements from Mojang Studios or trusted sources within the Minecraft community.
