we don't. congress has written several reports on how this embarrassing failure happened. we were going to build a small one as a proof of concept. that didn't work, we wasted a lot of cash on it too. so the next brilliant idea is to skip that stage and build a big one lol. that has, also, failed to produce anything useful so far. this is all public information. it's been in the actual news. you're just misinformed.
