"Scaling infinitely" is a pretty steep requirement. I wouldn't go there yet, either implementation of the blockchain technology is useful long before the insane transactions per seconds which VISA is handling. But yes, Ethereum has similar constraints as Bitcoin. Vitalik did some scalability blog posts on https://blog.ethereum.org/ https://blog.ethereum.org/ but it's entirely possible that any blockchain technology just won't scale as we would like it to (that is, as good as a centralized approach). OTOH, if there is a good technological solution, currently I have much more confidence that it gets implemented in Ethereum than in Bitcoin. The current infighting, bickering and actual threats and actions (e.g. DDOS at dissenting miners) is slowly but steadily destroying the Bitcoin community.
