CO, you've hit on exactly the reason that FFF printing isn't going away any time soon. As prices drop on resin printers, prices will also drop on home filament extruders that people can use to just recycle their old plastic waste into new filament. While resin prices drop, filament prices can drop to effectively zero.

Also, there's currently no easy way to print multiple materials on a SLA or SLS printer. When a low resistance conductive filament is developed (Filament with moderate/high resistance conductivity has already been made), it will change the game completely for filament printers. Right now a 3+ head FFF printer is a luxury, but when a head for conductive lines gets introduced, 3 heads will be essential.
