I did not pick them they picked me

• Bash
• Python
• Rust
• Scala
• Terraform
• TypeScript

The Bourne shell was cutting edge in 1977, and it still is today. I have aesthetics issues with it, but it has found a new happy home in cloud computing.

Python and Scala will take you far in backend and data engineering.

The gradual types in Python 3.6 and 3.7 are really a great help but they are very simple compared to TypeScript that probably has the most sophisticated type system these days.

Rust is beginning to make it into cloud infrastructure

• AWS Firecracker
• Fargate
• Google Fuchsia

Rust also seems like a natural choice for working with WebAssembly.

Terraform feels like a strange combination of Haskell and TypeSafe config. But it also fills a niche in cloud computing for: Infrastructure as code.

TypeScript is a roubust JavaScript and unsurpassed at describing and processing complex syntactic relations using its type system.
