Innovation tokens in serial is dangerous but in parallel is good.
Think of an innovation token as a novel problem.
A high chance that it doesn't work, but a low chance that it does work.
And if it does work, it's game-changing.
In serial: you need all of them to work, and the likelihood that all of them work diminishes super-linearly.
In parallel: if any one of them works, you get something game changing.
Each one gives you more chances for a game-changing result.
Innovation tokens are acorns.
