This is not a new era, I know there were slot machines in bars or on the streets before. Gambling is forbidden in my country so there are no casinos, naturally there are no slot machines. In our country, those who want to gamble mostly visit the island of Cyprus.
In Cyprus, I don't remember seeing it very common on the streets, it is only common inside casinos and hotels. It depends on government regulations in the future, but governments will be concerned about it becoming so widespread on the streets, if not all, then most.
