They care about your site being compromised or down, and your choice of tech stack has a lot to do with how likely those things will be.
You know when users complain about the lingering bugs, unexpected slow downs, and slow delivery of new features caused by tech debt (even though they don’t know that). That’s them caring about your stack, whether they know it or not.
Banks.
Do you know why banks are still running COBOL on new, old architecture, IBM mainframes? Sure, it’s in part due to risk aversion, ignorance and inertia. But it’s also because, if in the end the result is the same, then the tech stack doesn’t matter.
Very few people are tech fanatics, most people want results. They care when the products don’t work. They don’t care how you fix it as long as you fix it in a reasonable manner, within an acceptable timeframe at an affordable price.
Doesn’t matter if the customer is a billion dollars bank or a social network. Debbie thinks javascript is when the barista puts her initials on her latte and rust is something to fear when it shows up under her car. Too many devs forget this.
tbh I’m confident I can deliver bugs, slowdowns, and tech debt using any stack 😎
