That is incorrect. There is an inductive proof to that effect, but it violates
the mathematics of infinite series, when it tries to maintain a property of
finiteness over an infinite range of numbers that are constantly increasing.
One has to be careful that they are not using a method of proof which violates
the idea they are trying to prove. While the successor to a finite number is
always finite, that's because the successor represents the addition of a finite
value to that finite value. The sum of two finite values is always finite, but
the sum of a finite value and an infinite one is always infinite.

Well, then, there is an immense amount of inadequacy here.
