Because of the technology, the way we gamble also changed. Now, it's not necessary to go to physical casinos in order to play because online gambling made it possible to still have fun wherever you are as long as you have a gadget and internet. Just like what @serjent05 mentioned, some online casinos are coming up with new feature to change what we used to and it's up to the players if they want to try this new way to gamble. Anyhow, it's still different to gamble in physical casinos compared to playing online. If you want to socialize then nothing beats playing if you personally go to a physical casino because atmosphere and experience are quite different.
With so many online gambling users, there are currently many gambling companies popping up, especially in countries that prohibit offline gambling (traditional casinos). but unlike countries that legalize gambling, there are still many people who really like to socialize at offline casinos
gadgets are getting more and more sophisticated with internet processing speed and battery resistance, nowadays people can easily access online gambling sites via their smartphones (even when they are in a forest without electricity) as long as they are connected to the internet network
