It proves that net positive fusion is achievable here with known physics and technology (outside bombs which are useless). We had never done that before. This

It proves that net positive fusion is achievable here with known physics and technology (outside bombs which are useless). We had never done that before. This will probably unlock more funding. In the end a different approach is probably more likely to lead to a power plant unless truly gigantic advancements in laser efficiency can be achieved.
