Most web devs are familiar with javascript and typescript and are currently easily able to create products and solve problems for companies. They are much easier to find and hire compared to rust developers. So why should a company hinder its own productivity by trying to find rust developers because rust is technically safer in some ways? Or risk ruining the culture of its currently functional developers by forcing them to use rust?
