And there's never a serious consequence to the ones who did it. By then they switched to a new position somewhere else. Like most prima donnas. And this shows that deep, deep down they know they are fake.
Actually, another view is that there's nothing wrong with tinkering and DIY. Perl, JS, Redis all came from people hacking their own solutions (as far as I know).
Also, many big software orgs build extensive internal tools themselves.
Plus, making your own stuff is a lot of fun. You should try it sometime (if you haven't already) :)
What is bad is putting them in production when you don't have a clue about the domain.
Also, they have to have some clue about the domain, because the domain is their own problem and they're writing a solution for it. So I don't think we can really just someone as not having any clue about their own engineering challenges.... especially if they're working solutions to them....
Antirez said literally he didn't know about existing solutions when he went to write redis, and he and redis are awesome. nothing bad about that
but I get your point about bad solutions are bad but that's sort of a tautology, doesn't add much value, and who are we to judge someone else's solutions are bad we don't know everything about their use case.
Again... even if we can say that you choosing someone else's technology for your problem is not a good solution we just can't criticize the author because it's your responsibility what you choose. so I just don't think it's valid to criticize the author
They can be lifelong experts on their problem, yet have no clue about writing a database engine and low-level programming in general.

Nobody is born with knowledge. The difference is that Antirez studied previous solutions, studied how to do it, and then applied that knowledge right.
Instead, that person did the equivalent of building a bridge disregarding everything humans learnt about it since the Roman empire. It will not be a surprise if the bridge ends up collapsing.
