There are good and bad qualities to the CS events catered towards women. I think they are good for women of certain age groups (maybe 18 and older?) who might have been discouraged from or misinformed about the field. For young girls, these events are probably unnecessary and reinforce the stereotypes.

The events and boot camps made specifically for women to learn to code/learn about various opportunities are great, but I would hate for young girls to attend these events and learn about the gender inequality in case they weren't even aware of it.
