  • I guess my objection then is that I tend to take “just scale it up” to imply “all the tech development hurdles are done, we have a working prototype of the machine we want to build, we just need to construct a physically larger one”, and so was taking the process of improving the efficiency of the reaction to useful levels and figuring out how to make a significantly more efficient laser as “we don’t have this technology done yet, because we still have these milestones left”. In other words, we’re just arguing from confusion over different definitions of a word rather than the reality of what those words are referring to



  • Er, not really with fusion actually, unless you just mean “have made atoms fuse regardless of if it generates net energy or not” in which case we’ve had it for decades. We have managed net energy production if you compare the output of a very powerful laser used to compress the fuel to the energy of the resulting reaction, but crucially, the laser in question isn’t perfectly efficient, and only a fraction of the electrical energy put in is turned into laser energy in the beam. This means that we still don’t have net electricity production, and even once we finally get that, getting the tech efficient enough to produce enough electricity to be cost competitive will be a tough ask, especially as electricity from solar in particular has been going down in price of late.


  • if they were randomly placed, then couldnt you have a sponsor-block type system where instead of the ad segments being marked and skipped, information about the video is externally stored somewhere (like perhaps a really low res screenshot of the video every couple seconds, or some number generated algorithmically by a frame of video), and the results should be the same for all users for the actual video part, but if the ads are placed randomly, the ad section will suddenly not match the data other users had, prompting the video to skip until it matches again (with a buffer included if they remove the ability to move forward)
