I think it's definitely a start. Cuba will probably not change much until after both the Castros are dead. If Venezuela is any indication, socialist regimes in Latin America built around personality cults start to struggle once the personality of that cult dies. Castro's likely successor, Miguel Diaz-Canel, looks to be another Nicolas Maduro--someone chosen for their loyalty to the socialist cause rather than by their merit or charisma. Now that Cuba can no longer look to the USA as an excuse for all their miseries, there will be more pressure on Diaz-Canel to reform the country. Best case scenario, the embargo comes down, both Castros die before 2020, Diaz-Canel shows himself to be a cautious reformer, and by 2030 Cuba is a democratic country with a burgeoning economy heavy with foreign investment and entrepreneurship.
Worst case scenario, the embargo doesn't come down, Marco Rubio becomes president, Raul somehow lives to be 95, and nothing changes for the foreseeable future.
