Why? Same reason as with most people about most things: because their income depends on it.
I can't honestly say so, though.
Yet, I can say I am so excited for the future! For once, I don't want to wake up in the future — I'm loving being at the heart of it, seeing it progress and watching it allow people to be more creative and more empowered.
This has been my state of mind continuously for more than 3 years
