On the other -- of course they founded a company and got backing from Google. People get to work on what they want to, and they should, but I feel the same way about esteemed cell biologists starting hair startups as I do brilliant computer scientists working on ad placement algorithms. There's a bit of a shame in there somewhere.
Burn victims would like to have smooth skin with hair on it. Now I know this specific treatment probably won't help burn victims, but research on hair growth in general does.
Ultimately medicine is working towards a fountain of youth and if R&D can develop a revenue source from people who want their hair to grow back it's a means to further fund that quest for the fountain of youth and a reduction in human suffering.
It's not like people who buy toupees or hair transplants were going to otherwise spend their money on donations for burn victims.
We could say better hair leads to better self expression, confidence, etc even if we say its purely an ego/vanity source (which i’d argue, isn’t necessarily the case but for sake of argument lets say it is)
Ad placement algorithms don’t lead to a person’s well being increasing, outside shareholders/business owners which is tied to monetary gain.
perhaps you could say better ad placement for XYZ ad that promotes ABC net positive outcome means the work is positive, but i don’t see the inverse case with hair growth research that has high a magnitude of net negative outcomes on society as ad placement may have beyond:
1. Everyone gets better hair, so a lack of hair means societal pressure to conform
2. The treatment/therapy is patented, and prohibitively expensive where only the elite income brackets can afford it
To say more concisely, theres much more potential for an ad placement algorithm that hyper performs to be net negative on society than a hair treatment that hyper performs to be a net negative on society
(Provided it works, there are several such announcements every year but the actual progress is mediocre.)
Being an unempathetic asshat does.
Work on oneself. Treat other people nicely. Be surprised when they respond favorably.
IOW, they'd just be incels with hair...
A deep dive into why this is different sure would be an interesting article to read
