Incandescent light bulbs burned out at the speed they did because of an agreement between light bulb manufacturers to not make them better.

That’s totally true. If you go to Edison’s house they have light bulbs that have been burning for a really long time. Every tour someone asks, “why don’t my light bulbs last that long?” The tour guide replies, “because then you’d only buy them once.”
Also the bulbs that last forever are majorly undervolted. They last forever because they’re not run anywhere near their current capacity, and as a result, they emit way less light and their filament doesn’t degrade as fast.
If you take any old off the shelf incandescent bulb and only run it at 50v, it’ll last decades.

They also don’t produce usable amounts of light.

A big part of that is that those bulbs are never turned off. Cycling power is actually a large part of what degrades them.
