To be clear I do not think we should restrict the throughput of the network so that people can continue to run full nodes on raspberry PI's. I do not think this was ever the intention for Bitcoin either. It is true that there is a balancing act here, and that decentralization is effected in different ways. However everything considered I think that increasing the blocksize will be better for decentralization overall compared to leaving it at one megabyte.
You guys obviously have no clue as to what an 'example' is. I could care less about the Raspberry PI, but I know a lot of people using those to either mine or run nodes.
2. I have 2 TB storage but I guess average might be well above 1 TB today. At least 5x increase is reasonable in 6 years
Unless new technology comes up, no it isn't.
3. Rasperi PIs are dead path for the most successfull crypto imo. You dont release best games with minimum system requirements so you can please everybody. You stick to something like top 75% of user PC market and only this way you can release top product played by most. Releasing India game with basically no minimum system requirements will not give you a better seller...
You guys seem to lack some logic though. Who cares about the Raspberry in particular; take any model of a processor that you want. Where is the limit? This was discussed at a workshop IIRC; new nodes being unable to ever catch up to the network. You can't deny it now though, essentially you would push X amount of people with systems that are unable to handle the network anymore -> smaller number of nodes -> decentralization harmed.
As previously said, this is definitely going to happen the question is if it is going to be negligible.
