What commenters say

• The release of Mojo 1.0 is seen as a significant milestone, but some commenters question the decision to release it without open-sourcing the compiler and toolchain.
• Some argue that creating a new programming language is pointless in the age of AI, while others see the value in having a language that can compile to MLIR for heterogeneous compute and GPU programming.
• There is disagreement over whether the closed-source nature of the Mojo compiler is a significant issue, with some arguing that it is a major drawback and others seeing it as a necessary step before open-sourcing.
• The company's decision to open-source the compiler and toolchain in 2026 is seen as a positive step, but some commenters are skeptical about the timing and motivations behind this decision.
• Some commenters draw comparisons to other programming languages, such as C and C++, which were also initially closed-source, while others argue that the landscape has changed and open-source is now the expected norm.
• There are differing opinions on the potential success of Mojo, with some seeing it as a viable alternative to existing languages and others believing it has missed its opportunity due to the rise of other languages and technologies.
