Why Lazy?

Question

Why is there a trend for high-level programming languages now? People are even too lazy to create their own data structures!

Answer 1

I took a tour of a amazon fulfillment center a year ago. There was a big sign near the beginning saying “No one cares about your effort. They care about your results”
If you want to spend your life coding at a low level, that may seem like a very noble pursuit to you but it isn’t something anyone cares about.(unless you make complex software go faster). People want you to code for them to get results. Higher level languages speed things up.

Answer 2

To make the data structure well and efficiently requires a lot of experience, rarely is the level in the standard api (Java) surpassed. If something existing and cheap (free) can be used, then it is extra work. Either way, you need to learn how to use the existing ones. There are fewer cases where the standard API is insufficient or cannot be extended.
But It's great if you want to learn how these structures work internally, and what the people who develop them face.
