Almost every major change is made by convincing others to act because there is only so much one person can do. The probability that ano88888 is positioned in such a way as to start a car company is pretty close to zip.
Meh. The pen is only mightier than the sword when there are few writers among many doers. In this age of social media and microblogging, the pendulum has swung the other way and those who act stand out from the sea of voices passively demanding "change".
The mighty weapon is still the pen, it might is just dependent on how you apply it.
Tesla doesn't exist because Elon et al. went into his backyard and made a car, it exists because Elon et al. convinced a bunch of other people to cooperate on making a car.
Same with Jeff Bezos et al., and Amazon. Steve Jobs et al. and Apple. Bill Gates et al. and Microsoft.
Just posting on social media doesn't make your pen mighty, reaching out to people and convincing them to work on something does. On the other hand, social media is not a terrible place to "test" ideas to try and get an idea whether or not you'll be able to rally people to the task at hand.
No, I primarily meant Elon but used et al to include them as more minor "authors" (pen users). Elon appears to have been the primary "author" that actually convinced enough people to work for Tesla that it has succeeded to the extent it has.
