As a React developer I have the strictest policy to never go lower level than the browser and I never touch other fields of computing. I started my computing career in 1986 knowing only React and I'll get to the end of it knowing nothing else.

So maybe "close to the DOM" rather than "close to the metal"? :-)
On the other hand, if you ever want a project to get you out of your comfort-zone(/rut?) - check this out:
You _can_ go "bare metal" and still use your hard won javascript skills...

That's a big gap in your memory between 1986 and when React was first released in 2013. Or _maybe_ 2010 or 2011 if you were working inside Facebook back before they released it publicly...
You do realize why you're being downvoted, right? :D
