I believe Adam Back said that increasing the block size is already an absolute for the future of the network. But what Bitcoin Core will not do is to increase the block size to satisfy some group's political agenda.
Unfortunately, the Core team is what has kept Bitcoin back from scaling into a full-fledged cryptocurrency. Even if the Lightning Network aims to solve scalability issues, it's not the permanent solution. A block size increase would be mandatory to realize the full potential of the Lightning Network. As such, the bigger the block size, the greater the Lightning Network would perform, but too much block size would further centralize the cryptocurrency.
A safe bet would be to increase the block size 2x every 4-5 years to maintain the coin as decentralized as possible. Since Moore's law states that storage costs would increase over time and prices would reduce by then, it shouldnt be an issue if Bitcoin's block size becomes greater in the future.
Nevertheless, we'll see what happens once the Lightning Network becomes active and widely used in the mainstream world.
Everything is ok so far with Lightning Nodes surpassing Bitcoin Cash nodes in number. Hahaha.
That's certainly true, mate. Bitcoin Cash will become extremely centralized as it increases its block size to 32mb on May 15th. This will allow less nodes to become available on the network, as storage and bandwidth costs will increase. The blockchain will increase up to 32x than Bitcoin Core. Therefore, people would prefer to run Lightning nodes and Core nodes as costs will be cheaper in the long run.
Before we know it, nobody would want to run a Bitcoin Cash node as it'll be very expensive to do so. On the other hand, Bitcoin Core and Lightning nodes will be highly accessible allowing anyone to join the network without spending a lot of money. In the end, Bitcoin with its Lightning Network scalability solution, would prevail over most cryptocurrencies we know and love today.
