Dear Challenge members and organizers. I've decided to stop participating in this challenge. I understand that there are challenges of running this IT infrastructure, but at the same time I need to have a certain level of quality in order to be able to perform and deliver what I'm good at. The availability of resources is too unpredictable as it is, and I'm worried that the outcome will be a lottery, -or even worse- based on a resource landgrap competition! That uncertainty is too costly for me to justify investing much more time in this challenge going forward. I hope the infrastructure problems will be solved soon so that both participants and organizers can focus on the actual challenge. I also hope beautiful models come out of this challenge that improve the quality of medical diagnostics and patient health .There are more than enough participants to ensure that that will happen. I wish everyone good luck!
