The productivity and joy I get from working with this stack are immeasurable. I’ve been ruined in terms of having zero tolerance for the agony that comes with the JS ecosystem for example.
Very similar to Shopify. Rails for business line stuff. Go/Rust for performance critical services. React for front end. Python for Datascience/ML.
A truly modern language is Rust.
When Ruby made western presence it was clunky. No one knew what it was and it got stuck with that personality. It had an ecosystem too but never hooked in to the western world.
Java is tainted by Oracle and seen as "business".
And it's also weird how Postgres has made an uprising appearance. It was sitting duck back in the 00's. I knew it existed because as an script kiddie I could install a php forum and select it as a database backend but I never did.
Want to make a LCD display? You can simply by slapping a python library in to your code.
Ecosystems pull coders in. Thinking about it, it's probably why Perl was popular before with CPAN.
The old net was special but skills had to be learnt. Remember the days when you had one server for one service?
The new net is terrible but everything is handed to you on a golden plate.
All that extra complexity is great for the economy.
