- definition #1: "talent" doesn't exist or it's achievable by anyone because it's just a learnable skill. Skills can be improved. This is the meaning emphasized by M Gladwell (10000 hours), D Coyle (talent doesn't exist), Carol Dweck "growth mindset", Angela Duckworth "grit", etc.
- definition #2: "talent" is a ranking. This is the meaning emphasized by most people who are "looking for the most talented". E.g. sports teams for athletes, Hollywood for actors, Google/Microsoft for PhDs in mathematics and machine learning, etc.
If you're unaware of both meanings of "talent", you will always misunderstand what the other side is talking about. As a result, people will forever be bikshedding the word "talent" and stay frustrated that they can't convince the other side to change their mind!
The blog author of this thread also leaves out the meta discussion of "talent" and is using definition #2. The blog author (Jacob Kaplan-Moss) in my previous comment uses definition #1.
