After years of implementing no new functionality at twitter, Elon cut 75% of the workforce and in a relatively short time that followed they implemented:

Expanded Content Capabilities: Users can now post long-form content, including articles up to 25,000 characters, and upload videos up to three hours in length.

AI Integration: The platform introduced "Grok," an AI chatbot developed by xAI, integrated into X to provide real-time assistance and content summarization.

Job Search Functionality: X added a job search feature, allowing users to explore employment opportunities directly on the platform.

Financial Services: Plans were announced for "X Money Account," a digital wallet enabling real-time payments and fund transfers, developed in partnership with Visa.

Communication Tools: Audio and video calling features were introduced, expanding the platform's communication capabilities.

Content Monetization: Users can now earn income from engagement on their posts.

Many more things... tiered subscription plans, overhaul of moderation policies, community notes expansion, algorithm changes.

They were able to do all these things with a 75% reduction in workforce. Don't you find that interesting? If it had nothing to do with Elon, what would you think about it?

It's also been reported that X/Twitter is now more profitable than it has ever been. It's revenue may have shrunk, I am not sure, but even if it's true cherry-picking that fact isn't intellectually honest.
