I got into HBS 2+2!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

This is a very immature take. I suspect you are still relatively early career

the MBA program, in particular the Harvard mba, is designed for future CEOs and general managers. These are people that need to have incredible drive, deep domain spikes, but also broad and cross functional knowledge and leadership 

success at the top of the pyramid often is multidisciplinary: people relationships, marketing, personal branding, leadership, and technical competence all contribute to your success 

there is no institution on the planet that opens up more doors to the upper echelons of society than Harvard. That is particularly true from the many students they admit each year who don’t come from that background 

if you are looking for technical training you should be in a phd program 

if you’re looking to class and opportunity jump then you go to Harvard
