They are a &lt;i&gt;tiny&lt;/i&gt; research lab. The suggestion seems to be that one newer (now former) member of the lab just thought F-this we need to publish, get it out there and start moving forward.&lt;p&gt;If it is real, the level of investment in finding ways to make this stuff is going to explode. It may be hard to make, but that won&amp;#x27;t stop us from finding a way to make it on a large scale if it truly is revolutionary.&lt;p&gt;Further to that, from other groups studying it we will potentially find better and easer to make alternatives.</text></comment>
