well, if in this period it is a matter of cost, tomorrow won't be anymore. 4GB of RAM in the 80s would have cost tens of millions of dollars, now even your car runs 4 gb memory only for the infotainment systems, and runs dozens GBs of RAM for the most complex assistants. So i would see this achievement more as a warning, the final result is not what's concerning, it is the premonition behind it
