Yes, that is the common narrative. What the Hughes article makes crystal clear is that Edison didn’t iterate on 3000 different versions of the lightbulb because he was bored. He did so because most configurations were low voltage, high current - this required thicker copper which was the limiting cost to electrification - by finding a viable configuration that was high voltage, low current (and patenting that configuration) he could mass produce light bulbs and the necessary grid behind them at a cost lower than natural gas. An analogy is perhaps Elon Musk didn’t invent the electric car, but he released it in a form (along with a supercharger network) that made mass adoption viable over the competing gasoline based network. Following a period of over-infatuation with Musk, it may be likely that 140 years from now we condemn him as not really inventing the electric car, saying his patents over battery production technology were trollish, and hail Mark Eberhard as the true unsung genius. For obvious reasons that interpretation is problematic and kind of misses the point of what these people actually did.
