Intelligence can mean a great many things.

If we are simply making people better at cognitive tests then whats the point really? Nothing exciting there.

If we are making more Einsteins and Steve Jobs then Im more inclined to say we are increasing our intelligence in a meaningful way.

I think we need to be careful about our scales and definitions when speaking on the true nature of human intelligence and intellect otherwise we're all just blowing hot air. IQ is an antiquated measure of intelligence for example. If we are talking about extra IQ points then who cares.
