Moore's Law.
I believe the devs are working on the size of the blockchain, but it's not at the top of their list, and rightly so. They have bigger matters which require their more immediate attention.
You're correct to point out the growing size of the blockchain, but it's a relatively small problem amongst others.
Thanks for clarifying
Good that they take thier time to make it clear for you. i can really see you understand everything now and very happy with the response you get from them.The devs are actually very busy attending most important issues partaining the bockchain and will also face other aspects that needed attention too.
