My group theory is far too rusty to gather what is really going on here, but having looked at the Wikipedia article on SIDH the reason this might be of particular interest is it is a "post quantum" crypto algo - i.e. thought to be secure against attack using a quantum computer.
That is the only reason it is interesting, I think. It is likely inferior in basically every other way.
NTRU is likely the most accessible post-quantum crypto as it resembles RSA on convolution polynomials, if you squint at it. It's security is based off of Lattices (integer coefficient subspaces).
This one looks like it requires only a (slightly advanced) undergraduate level in group theory, but there are big gaps from being just slides. Of course, I could actually only think I understand it and be completely wrong. ;)
