I kinda think that too - all the credit is going to the guy who happened to lay the last brick. Still I don't think there's any avoiding that, because everything does build on what has gone before. It is interesting to speculate about which innovations were the most original, or involved the greatest creative and imaginative leaps. People will disagree even more about that though, and it is easy to say an invention was obvious once someone else has invented it.
Personally, I think the car involved practically zero innovation - it was an obvious application of technology that already existed. Same for the lightbulb really. I think I remember learning that a lot of experimentation required to find the right material for the filament, but once you have electricity and you see it sparking and maybe making wire glow a little, it is not hard to see that that kind of experimentation is worth doing. I think the printing press was more innovative - I can imagine people saying "what's the point of that contraption when a scribe will work day and night for two boiled eggs and a tallow candle. Anyway the letters look all funny". The PC is also a bit like that.
I don't think the clock belongs on the list anyway, but that again is incremental problem solving rather than a flash of inspiration. The use of electromagnetic waves to transmit signals is much more innovative, IMO, but that doesn't figure unless we say that "telephone" covers it.
