Definitely not. Five year survival rate for stem cell transplants is about 50%. People with HIV now have effectively normal life expectancies provided that they're treated. Even if this worked reliably, it would be _very_ much a case of the cure being worse than the disease.
That said, IIUC the whole stem cell transplant procedure is unpleasant enough that it still might not be worth it.
"The major cause of death is relapse, which accounts for approximately 40% of all deaths, followed by infections at 25% and graft-versus-host disease (GVHD) at 20%."

A good friend of mine died from a C. Diff infection in the hospital after a bone marrow transplant. It is very risky, especially with an imperfect match.
That said, you can help make it less risky! This used to be called "Be The Match", not sure why they renamed it but you could save someone's life by registering to be a donor:
You get to save the life of a stranger AND they give you a t-shirt. Win win!

There is at least one documented case of someone using anti-retroviral therapy, getting their viral load down to undetectable, stopping the therapy and remaining undetectable for years without continued therapy. They use the word "remission" rather than "cure" because there are fragments of viral dna that remain in your cells and it's possible for a "reservoir" of inactive virus to exist and activate, so there will always be regular testing involved in any attempt to eliminate the virus entirely, but whether it technically counts as "cured" becomes a nearly-moot point when one is able to live the same way that someone who has never been exposed lives save for the testing.
Still, that is big news, considering how many people have died from HIV, and how many still live with the virus. Treatment has come a long way - I remember how it was practically a death penalty in the 1990s; but a complete cure would be so much better than depending on medication for the rest of one's life. I don't think this is the breakthrough, but it is proof that search for a cure is not futile.
