Of course we are evolving
The fundamental laws of evolution still apply: changes in attributes are filtered to favour certain attributes above others depending on the "fitness function".
All we have done is change the "fitness function" - the function that weeds out poor candidates and allows better candidates to continue. To be clear, that is poor/better as judged by the fitness function, not by any moral judgement on my part.
We've changed the fitness function through various means such as medicine and social engineering.
People that would have died due to various medical defects are now kept alive to lead normal lives and procreate. Genetic dead-ends such as infertility are now reversed. Women with conditions that would have caused death during childbirth are now kept alive and can breed to pass on their genes.
The move towards smaller families was a result of medicine. No longer did you need to have 10 kids to keep the next generation around. Now you need 2.3 kids to do that and the "fitness function" changed to prefer having fewer kids and investing more in them so that they can get ahead with better education and the like. This put them ahead of the families that had 10 kids but could not afford to educate them.
In many countries social engineering has changed that yet again. Free education & benefits mean there is no longer a penalty for having many kids. The state (aka the taxpayer) will pick up the bill for education, feeding them, etc. This change to the "fitness function" now favours the families with 10 kids again.
Valuable survival traits such as being able to run fast are superfluous thanks to transport. Being big and strong - no need, I have a gun. Surviving heat - replaced by air conditioning. The list goes on.
Evolution never stops, it just changes direction.
