Top modern researchers/practitioners do seem to value simplicity heavily, but can't say the same for most. The propensity for misuse of abstraction/models/data/theories is pretty high from what I've seen. That's my view. You are free to disagree!

PS: It is always better to rely on older sources for illustrations, because they have lived their life fully and you have documentation of their lives + effects of their efforts. It is not a good idea to rely on living people to illustrate principles.
