Nah.  As I can think a lot of people’s missing the basic things regarding difficulty, difficulty re-adjust every 2016 blocks and not in x weeks, the network params just want 2016 blocks every 2 weeks  if those blocks took more than 2 weeks difficult goes up if took less than 2 weeks difficulty goes down.
That means if the governments like I read above a scenario tha stop meaning forever or put out countries of big mining farms the difficult re-adjusting can take in a worse scenario months as not weeks. All those are scenarios, even if it happens developers can solve it, you should not worry.
