I'm not being pure cynical about his ability but such comparison is flawed in every possible sense if you look at more objectively.
Firstly, an IQ of 160 at such tender age could have a few implications- 1. It's like what the article has claimed. 2. An advancement of growth where he reached his peak at a much younger age, so that may be where his peak might have been.
Secondly, there is no comparison with the likes of the greats simply because they have already achieved something which might be yet too distant to even talk about little Oscar now. Those people are typical representation when it comes to the talk about intelligence, but on top of that, we ought not to forget that true greatness lies in the manipulation of such gifts- and perhaps the greatest intelligence lies in the ability to use it.
Moreover, like what you've said, he lives in the era of technology and science. That aside, the amount of attention this sheer report has poured upon him is already enough to cause an immense drawback. Then perhaps we would like to address to the potential source of the kind of tools that would be available to help him grow into an unprecedented talent.
How about this? We look back at the likes of Einstein and Hawkins' lives. Both emerged as (to put it bluntly) unsightly candidates for greatness. The former was a much-loathed character back in school, and he did not even complete the proper education, but was fortunate enough to gain access into one of the top colleges. The latter was an unfortunate gentleman who succumbed to illness at the peak of his life. Nevertheless, none of these deterred them, and they proved themselves to the world that they were just as capable, if not more capable than anyone else in the world. Neither of them had had an illustrious childhood achievement, nor did they exhibit any forms of anomalies in their lives. So it's perhaps safe for me to say that the predetermining factor of their success is more of their attitudes towards things rather than their ability to understand them.
I mean, just to bring one more person into the picture. Everyone knows things fall when released in the air, but it was the one who questions the normalities that bring upon revelations to doubts. With that in mind, whatever you claimed to be the enhancing factor could very well be an undermining factor in all aspects. Especially when it's uncovered at such a tender age, especially when there are gonna be so much more specialised "talent-based" curricula that's gonna be designed for him. Is he gonna become one of the greats then? The possibility is there, but I highly doubt it.
