The only thing is that this is not an integrated circuit at all. It's a proof of concept, in that all the components are made of silicon. The wiring is another matter.
Bob Noyce at Fairchild patented an actual integrated circuit, with metal lines plated on the silicon instead of the wires of Kilby's invention. The resulting patent litigation made many lawyers rich.
Similarly, the 1946 ENIAC was not anything like the computers we use today, but Turing et al's 1948 Manchester Baby is thoroughly modern in its architecture.
