You can be sure light bulbs no matter the type will never reach even 5% of what they could reach if research would focus on longevity instead of controlled failure.
I presume the tech was first developed in tandem for street lighting, and then carried over to household lighting because the government said so.
It's interesting as it is a common management consulting case study. As another comment mentions, most bulbs don't even reach their current full lifespan.
