After a few more major breakthroughs we'll be where fission was in 1942 after Fermi made the first man made neutron chain reaction. After that, we can see what a practical electricity producing plant looks like, and see how much people actually care about small amounts of tritium radiation.
At the moment fuel costs in fission are like 5-10% of total costs for a fission fleet. In fusion it could be lower, but that will not be any means mean the overall system will be cheaper.
We'll have to see the cost tradeoffs: fusion makes much less radioactive material per kWh than fission (but it still makes some) vs. simplicity. Fission is relatively trivial: just put special rocks in a grid and pump water over them as they pour out their star energy.
Progress is good and exciting, but I don't see any reason to think this will have major implications for energy systems anytime soon. Would be happy to be wrong though.
Disclaimer: I switched from studying fusion energy to advanced fission 16 years ago.
