Does it mean you can no longer easily tell if a process has gone crazy and takes high CPU usage without a fan and you also can't even feel the slow down.
That is true in many situations, like a remote server. That's why we have top on the commandline, or iStat Menus. But I'm not sure if iStat Menus actually works on the new machines.
I was wondering something similar. VSCode tends to fly off the handle every once in a while and the only way I notice currently is a subtle lagging and the fan spinning up.
Though recently I switched back to VIM so perhaps this won't be an issue anymore.
