Usually true for graduate hires but lateral hires of experienced devs are more uneven in quality. Where I work, campus recruits are like geniuses, while some experienced engineers are just buzzing through. I remember one of them told me he never used github, after working for 6 months, when we have github enterprise in our own company
This is just ridiculous. The other points may/may not make sense but drop direct-x for vulkan? What? It'd have made more sense to make Direct-X open source than just dump it like it's useless. It's not like windows drivers for GPUs don't support vulkan.
Direct-X has had a history of being the superior graphics API to OGL. Now, VULKAN evens things out a bit but just dumping so much of RnD for nothing doesn't make sense
