It's also popular to say Edison did not invent the light bulb. It is correct that he was not the first to invent a glowing wire. Edison's key innovation was the thin, high resistance filament which used high voltage and low current. That design was said to be impossible by all the experts of the time, but it is what made the light bulb practical and useful.
Edison's light bulb was attacked on all fronts in patent court for years, and he beat them all.
He invented the light bulb.
Ironically for Elon Musk, early electric cars mostly used Edison batteries.
"Swan's carbon rod lamp and carbon filament lamp, while functional, were still relatively impractical due to low resistance (needing very expensive thick copper wiring) and short running life."
It also mentions the high current.
As I remarked, Edison's breakthrough was the thin-filament high voltage, low current lamp, which made it practical.
Don't forget the audio recording industry, electric car batteries, mining advancements, the carbon telephone microphone, innumerable major advances in telegraphy, the electric power utility, etc.
e.g. It's not that Edison invented a light bulb - he created the first power grid. It's like inventing an internet client, and the internet.
