Come back if your child is 8 or 9 and still doesn't and even then it's not necessarily indicative of anything. I know kids who were socially awkward at that age and turned out to be teens with a lot of friends and no red flags to indicate any issues like ASD.
This, but I'd say age 5-6. What you are describing is pretty normal in language delays and you will see it clearly as the child gets older. At age 2, its very hard to tell and could be anything.
