I want to make a parallelism, or maybe i can say a historical parallelism. Or analogy whatever you want to call.
When Bitcoin was born we cant think in have the net in our hand, maybe we can have that in a laptop, but now you can have the full net in your hand in a smartphone.
500 gb its nothing for today tecnology. So imagine in ten years more where we can be. Maybe in our wrist in a smatwatch. Your wallet and the whole bitcoin core in your wrist.
Technology has changed quite a lot since 2009.
Yes, 500GB is nothing for today. And following Moore's Law, in ten years we should have devices holding up to 16TB (doubling every two years) that are as common as 500GB devices are today.
I mean, you can have a laptop today with more RAM (64GB) than a hard disk in 2009. Advances in technology have been amazing.
