I think you could make the argument that people working from home don't drive as much and so are putting less wear and tear on their vehicles which mean they last longer which means they aren't getting replaced as often which leads to reduced new car sales.
Of course, I think one could also make the argument that people are realizing what a POS Elon is and there are more and more electric vehicles to choose from which is probably the more likely reason for the reduced sales at Tesla.
You can do everything you need to do on an old laptop... you don't need a desktop. You just need to make sure you disable any of the power saving settings so it can stay on all the time but then enable a display-off type of screen saver.
