Honest assessment
Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Delta is written in Rust, which has a different syntax and paradigm compared to more popular languages like Python or Java.
Due to its niche language choice (Rust), Delta may have a smaller user base and fewer community contributions, tutorials, and forums.
As an open-source project with rapid development cycles, Delta might introduce frequent API changes that require significant updates to existing projects.
Setting up a Rust-based environment for machine learning can be complex due to the need for specific toolchains and dependencies not commonly found in more mainstream ML frameworks.
