I noticed a trend that engineers think all engineering is just like their own job.

The fact is that only few engineers can code in a single language to build the product they are working on.

Sure a kernel device driver dev can write 100k lines of C over a year and memorize every API.

But many product devs have to land code in 4-5 repos & languages. e.g. a bit of python, PHP, c++ & SQL just to complete one use-case.

For those in one language with narrow API dependencies, IDE may seem redundant. But if you are contributing code across multiple stacks & APIs, IDE is a life saver.

Lesson: Engineering is very diverse, and don't assume that tools that work great for you scale to other roles.
