Indians come

I see a lot of people address the GE CEO as 'Sir' under his tweets. I have seen that elsewhere as well where indian people just address celebrity type/sometimes not even that people as such. Why do you guys give them so much respect? Or is it cz of the 'caste' system?

Just as a sign of respect

It's just a title out of respect and its not only with Indians. Many cultures do it if im not wrong

I'll just say bhaiya or something not sir cuz he's older than me

? It's just as a sign of respect

Everyone has a different way of addressing people.

Japanese people use sama sometimes, Indians use Sir/Mam. Spanish people use Senor sometimes. It’s just a way of addressing people
