The top commment though is just wrong. He says Q would be 0.375 with modern lasers. Which would be worse than the result announced today! Q is a factor internal to the fusion reaction, so upgrading to more efficent lasers would not change Q.
Presumably he means something like total energy efficency would be very close to breakeven with modern lasers. You can tell how dubious this is from the fact no one involved in the project says anything like this. In fact, breakeven is still two orders of magnitude away and I don't believe anyone has suggested anything more optimistic.
Almost everyone in the top of any given subthread is approaching it very realistically.
