I don’t worry about myself either I have a server totally allocated to bitcoin with 32 gb of ram and a 2TB ssd (I can literally put the UTXOs set in my ram) I’m especially worried about small nodes like raspberry pi 4.
I also asked myself the question how far a raspberry can go, whether at the IDB level (it takes a week at the moment) or just to stay synchronized with the network unfortunately it is always unanswered.
