Your comment adds nothing new to the frequent and tired war (native vs electron). I get it, you prefer Vim and Sublime (I find this quite funny because I can only suppose critics attacked Sublime Text with the same arguments you use now)

Either way, Atom/VSCode have developed a large following which encompasses lots of talented and smart people. They both cannot be completely summed up with the description "slow and clunky." They are absolutely not perfect, but if you really cannot see any of the many reasons people use them, you're being left behind and I strongly suggest you refrain from commenting.
