Tangentially: Microsoft Teams and SharePoint web infuriate me daily. All the functions that should be separate programs are rolled up into one inseparable window forcing you into a single task workflow.
Want to have two folders open at once that you can drag between? Want to copy a file to your desktop? Read a message from a colleague while looking at a planner item? Pretty much any basic task that Windows 95 can handle with ease? You're screwed.
These are all things that should be separate programs handled by the OS and a samba share. The MS Office ecosystem has regressed massively over just a few short years thanks to teams.
10 micron (0.01mm) is pretty reasonable tolerance for a lot of stuff. The laminations in Tesla's motors will be held to somewhere around that, possibly even tighter. Things like motor winding insulation coatings will be far tighter.
For something like body panels or plastic interior pieces it's utter overkill and a waste of resources.
