That’s a far better comparison than other offered. Nokia failed not because Symbian was outdated, but because they tried to have too firm of a grip on it and it didn’t evolve fast enough. But yeah, I can see that happening if Toyota decides not to share their tech with others and hydrogen doesn’t end up being wide spread as a result of it. Not sure if they’ll go bankrupt but still. Honda once almost did when they went all in on Wankel engines.
