The attitude this person portrays seems to fit in line with that. Defending your position with arrogance and irritation shows everyone a great deal about you.
I'll go ahead and lump myself in with the rest of the group that remains thoroughly unimpressed.
Visual Studio Code is amazing. I started using VIM on my Amiga 500. I use VS Code 90% of the time now.
RStudio is and was life changing for programming R
I use Discord everyday and use it as a real time Reddit for many non-gaming communities.
When your dev machine has 16gb RAM and at least a quad core processor, you're not exactly going to be benchmarking how well you manage memory space or complexity of execution.
Time saving is a huge factor in why apps are developed. There is always a balance between performance/resource usage and development time.
Your talk of balance is ironic considering the subject. It's absurd that a single blank window with no content should spawn multiple processes and consume over 100mb of memory before any logic has been added. Demanding better would almost certainly be met with calls of selfishness so I'll settle with contempt.
