Exemplar of the state of synthesis, 2025?

Who is pushing the boundaries of what can be done with synthesis right now?

I'm not talking about who integrates synthesisers into interesting compositional structures the best, or makes the most interesting musical arrangements. I'm talking about electronic synthesis itself. Who is on the cutting edge of inventiveness when it comes to sound synthesis?

Alternately, is there any artist whose work comprises a remarkably wide range of what is possible with synthesis, such that it functions as a "catalogue" of the state of the art?
