According to Dr. Ken Regan, no. Players at the same rating even across different eras are approximately equal skill. In other words today's Hikaru Nakamura is stronger than the 1972 Bobby Fischer. This shouldn't be too surprising, given that Nakamura was able to study Fischer's games and learn from Fischer, but not vice versa. The methodology is by matching ...

In addition to number of games played, draw rate is a very important factor. The top players will mainly have their ratings brought down by draws against lower rated players. For high level chess, blitz has an 18.5% draw rate compared with a 30.8% for rapid, and 36.9% for classical. Shorter TC allows super-GM level players to do weirder things to bring GMs ...

So the ratings there have no relevance to the current scale used by modern rating systems. The second chess rating system, the Harkness system used by USCF starting in 1950, already is calibrated almost the same as modern rating ...

Everybody seems to agree that "ELO inflation" is real (I found an article from 20 years ago claiming this exists)...except scientists. Here is a 2011 paper that vehemently denies the phenomenon; the abstract says that only little inflation happens, and the players really get better. https://ojs.aaai.org/index.php/AAAI/article/view/7951

This is actually a very interesting question! Actually, there were not many 1700 rated players 50 years ago because most ratings started above 2000. With the evolution of computers, it is very plausible that a 1700 player now is much stronger than 50 years ago. Nowadays, openings are spoon-fed and many references are available whereas those days every day ...
