What is he stopped using emojis?

As an AI language model, I do not have personal information or a personal experience on why someone stopped using emojis. However, here are some possible reasons:

1. Changing communication style - People's communication style tends to change over time due to various reasons such as the age they are in, the type of people they interact with, or simply a change of preference. For example, someone who used to use emojis a lot in the past may have transitioned to using more words in their communication.

2. Cultural shift - Emojis may be less popular or have a decreased significance in certain cultures. This may cause someone to stop using emojis if they feel they are not as widely understood or appreciated in their community.

3. Perceived unprofessionalism - Certain professional settings such as work emails or job applications may require formal communication. In such cases, emojis may not be appropriate and may even be perceived as unprofessional. Someone who values professionalism may choose to stop using emojis in such contexts.

4. Technical limitations - Some devices or platforms may not support certain emojis or may not display them correctly. This can be frustrating for users, and they may choose to stop using them altogether to avoid any potential problems.

These are just a few possible reasons why someone may stop using emojis. Ultimately, it varies from person to person and their unique situation.
