I disagree. I think Ruby/Rails is a good example of this. They maximize on developer happiness but that doesn’t stop users from using a bloated rails app. Take a look at GitHub/GitLab as an example of a Rails app I guess?
I don't see how end users suffer from using Rails. Server side rerponse time is a very small component of page load time for most websites. It's different from being forced to download and parse megabytes of JS, which consumes CPU, battery and time.
And now that developers make the visitors pay for the load (through their electricity bill, and also through their mental state), they don't give a shit about how much the users will have to pay - and thus how much electricity will be unnecessarily wasted on a global scale.
Abstraction for the engineer should not come at the expense of the person on the other end of the wire.
