I don't think anyone is necessarily saying what she has done isn't amazing, profound and admirable.
My comment was to the fact that she pretty much gave up everything to accomplish that. Was it necessary? Could she still have achieved what she did if she had friends or took even one day off a week? Maybe, maybe not.
My point was that it shouldn't be all or nothing to create a successful company. Many entrepreneurs, myself included have given up all of these things (at least temporarily) in the single minded pursuit of business success. I still work way more than I probably need to but also make time for other things.
Just because she is doing something lifesaving doesn't mean I shouldn't want her to also enjoy her own life. I would have said the same comment if she made the next WhatsApp instead. Good on her that she's saving lives. Also good on her if she wasn't and just accomplished something big.
To clarify (at least my own point), if you love what you do and don't need friends etc then that's great and I wish you all the best. Whatever makes you happy. If instead you like having friends, dating, a day off etc then don't feel you absolutely need to remove all of that to make a successful business.
