It's too late to make it happen because they should have fixed these network problems long ago before Neo,Eos and Cardano existed. Now the Eth-like altcoins will make sure that they will be much better and that will make Ethereum plunging down sooner.
In my opinion it's Neo, Eos and Cardano have to prove why they are not worse than ethereum. Of course eth must be improved in order to keep up with progress, but this is true for any crypto currency.
