most definitely. now that we understand the problem, good crypto
primitives are designed in a way that the naive implementation is the
safe implementation. or at least it is easy to get it right, and it
isn't a huge compromise. that is the design philosophy behind salsa,
curve25519 or keccak, among others.
but aes is old, and nobody had a clue about side channels back then.
pity many people in the field still don't know about them.
