We already have filter-free vacuum cleaners and LEDs are not light bulbs. I'm just saying that everything will eventually be like that.
Discussion
There are two kinds of filter-frees IMHO - the kind that require paper bags, and the kind that blow dust back out everywhere. A cyclone can only do so much. The human avoids doing one job only because the machine avoids doing another.
LEDs are modules, not simple bulbs, and they suffer failures too, admittedly not at the same frequency. They still need replacing and we not automating that...
