The documentation for on String is pretty clear it returns a new String.
A String is not an Array of Char in Ruby.

... and you could use #= to get the result you're expecting.
x = "abc"
x[0] = x[0].upcase
x
#=> "Abc"
By the way, if you want to "capitalize" strings in Ruby you could try
the tips at How to capitalize the first letter in a String in Ruby - Stack Overflow
