I suppose whether or not to do postgraduate study depends on what sort of career you want to pursue and what skills you need. There may well be other ways to acquire those skills, though a benefit of an MSc is that it is very widely recognised.
(That's just my initial impressions going into this, mind.)
You should not consider a MS in CS if 1) you want a cool looking resume, 2) you want to delay making decisions about what you want to do in life, 3) you think MS will make you a better tech founder, 4) you think you will get paid more / raise through the ranks faster with a MS.
Everyone will tell you that an MSc will not get you more money. This is technically true. However, if it gets you into a career that you love, it probably will get you more money, because you'll do a good job (all things being equal).
I thought, people who wanted to be a teacher or researcher considers MSc.
