Hello everyone, my name is Alex and this is my first post on LessWrong, so each answer to these questions is highly appreciated.

Quick disclaimer: I am not an English native speaker, and I used AI to check the spelling.

I would like to validate the following hypothesis: 

Many valuable problems go unsolved not because of lack of talent, but because talented people can't find each other or the right problems to work on and they lack the tools to do so effectively.

Questions:

1. Have you experienced this? Tell me about the last time you wanted to contribute to a hard problem but coordination failed, or you couldn't figure out how to contribute effectively.
2. How do you currently discover which problems are most important to work on?
3. In the past 6 months, how many times have you discovered someone else was working on the same problem as you, but you found out too late?
4. What platforms have you tried for finding collaborators? What worked and what failed?
5. If coordination was perfect, what would you be working on right now that you're not?
6. What do you think is the biggest barrier to collaborative problem-solving on global challenges?
7. Is coordination a real bottleneck for working on global challenges in your opinion?

I am really looking forward to read your answers and am very thankful for everyone that takes the time to provide their insights.
