Hello,
I don't agree with some things you comment, for example, I think that the stack with which you develop something is very important because in the future it is almost certain that someone else will have to maintain the project.

And not only that, if you choose the wrong stack, for example, you can also have many security problems in the future. What happens if you decide to use a language or framework X and it is discontinued the following year? Who is going to fix the security problems that will appear?

This is even more important if it is a big project where more people work. Always be careful with the stack you choose and use consolidated and well documented technologies.
