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 so oversimplified that it borders on being a lie. Yes it happened, but the why of it wasn’t as simple as just “sell more lightbulbs”.
I can’t link it right now, but go on YouTube and find the channel technology connections. He does a deep dive into the history of the light bulb and the phoebus cartel. TLDR: believe it or not, it was actually a good thing.
Does that explain why he did a 40 minute video on why microwaves from the 60s were better, but have since become shitified? To promote toasters instead?
It was neutral at best, it was still a conspiracy to reduce choice in the market in a way that was beneficial to them.
Yes, the excuse they used was that it prevented people from creating light bulbs that were of poor quality, and had an unpleasant color to them, but it also was profitable for them to do so.
It would have been a race to the bottom. The same way it happens with other products today. Some number bigger = better marketing = selling more = others need to do the same or go bankrupt = everyone does it.
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.
