For the first release in 2012, the creators of Julia summarized their goals and motivation in a blog post [Why we created Julia](https://julialang.org/blog/2012/02/why-we-created-julia) interestingly.
In their 2012 inaugural blog post [Why we created Julia](https://julialang.org/blog/2012/02/why-we-created-julia),
the developers provide an insightful and funny overview of their objectives and motivations for creating Julia.
