All the current challenges facing Bitcoin as regards to Block size/Segwit are clear indication that Satoshi never anticipated a highly successful Bitcoin in a short time.
Nonsense.
Block size limitation was not in the initial white paper or BTC implementation. It was introduced as an anti-DDOS measure later, and was always meant to be increased when necessary.
SegWit also was not part of the original BTC, but a fairly recent hack and a temporary measure with questionable benefits.
