Yes, i believe magnus will break 3000 in a few decades to come since his chess knowledge is on a whole new level to previous players. He was even able to beat Karpov and draw Kasparov when he was 13 and just an IM
Will Magnus Carlsen be the first player ever to break the 3000 barrier?
Never, 3000 is way too high, Kasparov was 2851 in 1999 and just beating that is tough enough, a great player like Anand never had a single 2900 performance in his career as far as I know.

I think once more players are able to hold ratings of 2800+ we will see 2900's. That still seems to be a ways off though. But certainly someone will one day crack 3000, when there are quite a few 2900's and many 2800's. Not sure we will see it in my lifetime, but the new generation of chess is upon us and growing to be quite strong. We shall see.

yes, but he is overrated, inflation in fide ratings has pushed his rating upwards
Yes...the highest ranked chess player is overrated.
You are making an unreasonable prediction. Magnus Carlsen is world class and it's unlikely he'll ever make 2900 much less 3000. The performance requirement for a human just isn't practical. He would have to win constantly, not only to offset huge ELO losses from games he lost, but also to offset draws too. The only way he can reach 3000 without simply winning most of his games is if other players have an ELO of like 2900 as well, if they don't, and most players are still at 2700s then draws would hurt Magnus alot as well. 2800 is extremely good already, so really it doesn't matter in the end

Rating only tells you how good you are compared to others in the pool. It doesn't necessarily reflect how good you are qualitatively.
If you put a strong expert in a pool of beginners, it is probable that the expert may easily break the 3000 rating although the expert's playing standard is only at a master strength at best. This is called rating inflation.
If you put a super GM in a pool of only another strong GMs with no beginners, no masters, nor anybody less than a GM. I am pretty sure that the super GM may not even break the 2000 rating (Let alone the 3000 rating) despite the fact that the super GM plays at a super-human quality. This is called rating deflation.
In fact, Capablanca at his peak (if ELO rating existed at that time) may have reached the 3000 rating. Note this rating does not reflect how good Capa is qualitatively, but rather how good he is compared to others in the pool. Capa went undefeated (lost not a single game) for over 8 years while he was active participating in many strong tournaments.
So will Carlsen break the 3000 barrier? It depends on the pool. If there are more idiots joining FIDE in the coming years, Carlsen as well as others may reach the 3000 mark. If there are more little Carlsens, little Svidlers, and little Anands joining FIDE, then it will be difficult for Magnus Carlsen to reach 3000 (or even maintain his existing rating).
3000 rating is out of bounds for humans to reach; Magnus Carlsen is a chess monster but there will always be other extremely strong competition.
At best predictions he would exceed kasparov's 2851 elo since he goes in undefeated streaks, but his skill is not far superior to 2700s and 2800s to be 200 points stronger than those super GMs.

Hankas is right. A rating is only a number computed based on past performance among a pool of players. The number itself has no intrinsic "meaning" of worth. Everyone seems to suffer from this fetish. So the answer is: who cares??
Kramnik isn't going to get too much higher, although he may stay over 2800 until he retires
Only if he retires today, since he'll be 2799 on the July list. :-)
Capa went undefeated (lost not a single game) for over 8 years while he was active participating in many strong tournaments.
It was only three tournaments, one of them the weak Hastings 1919 with Capa as the only top player. New York the year before wasn't too strong either, with Janowski and Marshall as the highest ranked opponents, and they had passed their peaks already when they lost their title matches badly almost a decade earlier. London 1922 was quite strong though.
Comparing July 2002 and July 2012 the differences aren't big looking only at the actual numbers. Two 2800 rated players, ten years ago #1 was 2838 and is now 2837, #2 then was 2809 and is now 2816. Going just by that it doesn't look as if the top ratings will get close to 2900 anytime soon.
No he won't.
However, with time will come more rating inflation (unless it's addressed) and then someone might. It'll take quite a while though.

yes, but he is overrated, inflation in fide ratings has pushed his rating upwards
How can a man who is constantly playing the best in the world, and increasing his rating on the back of that be overrated? Nonsense.

Because the fide rating system has been inflated starting at some point (i'll have to look into that). When I say overrated, i mean not that he isnt any good, but that carlsen can reach 3000.
If Kasparov played todays new generation, he would still be the top player, and reach higher than his record 2851 BECAUSE everyone around him is high rated. If everyone around him was lower rated, like what happened in the 1990's, than no matter what his strength, he wouldnt reach 3000.
As someone said, the rating only shows how good u are compared to those around u.

Considering Magnus Carlsen is only 21, and already has a Elo rating of 2800+, is it probable that after 5-10 years he will break the 3000 barrier and become the first human player to do so? That I believe would be a great milestone not only in chess but of human capabilities in general. What does everyone feel about this?
