What about Cloud Environment?

Do you know that writing code efficiently can also save money for the company? If you try to write code that burns bandwidth or CPU cycles without even attempting to optimize it, it's gonna cost you an eye at the end of the year.

Software optimized for the slowest hardware possible actually does saves money, which helps also to reach the goal of doing more money, since more hardware is being supported, not only the cutting-edge one.

I've seeing now this infamous trend also on Android Phones boosting 90-120 Hz screens. If applications get optimized to run on these phones, whose CPU is also strong, obviously older phones are suffering and become sluggish.

Seriously, try to write code as your target platform is a Raspberry Pi 1 model. If works on it fast, it's going to be fast everywhere

That's true, but it really depends a lot on the kind of software you're writing. If you're Google or Facebook and make fractions of a cent per pageview despite doing an enormous amount of computation then optimizing your code and infrastructure is very important indeed. On the other hand someone like Airbnb is very likely to make tens or hundreds of dollars off a handful of pageviews, so cloud costs are much less of a concern.
