No one in their right mind starts a project with Oracle.
This isn't about the technologies themselves it's that Oracle are a pain to deal with. They constantly hit people for as much as possible. At an old job, we had an oracle blade system that had a dead blade. They wanted 60k for a new blade, and we would have to renew our support contract first (cost plus penalties) before they would sell it to us.
Another place I heard about, they hit a company for $800k to bring them back into compliance and then wondered why the company didn't want to buy more licenses after that for new projects.
I had to spec out a server not long ago and our sales rep wondered why I specced the machine with fast drives, tons of ram, fast CPU but only 12 cores. "Oracle licensing" It was easier to make a fast machine and go bare metal than deal with the quirks of their licensing system re Hyper-threading (it's a considerable speedup on Oracle) than to worry that I set up the VM system the wrong way and would be out of compliance.
Their attitude in recent years means their stuff ends up mainly being used in places where they can't easily be phased out but never for anything new.
