Prospects for commercial Unixes?

Question

Solaris

The purpose of this question is to find out from those who are related to the administration of the Solaris OS (and commercial unixes in general) about the thoughts and development trends in this area.
The fact is that over the past few years, I have been observing a decline in offers from employers in this direction (I'm not generalizing, just my IMHO).
I admit that I have played out paranoia, a midlife crisis, and so on. But what if the economic crisis\vendor policy\or something else is to blame.
Yes, commercial unix's have always been considered by those companies that are willing to pay for support with all the consequences, or are tied to a particular platform. But after all, there were projects, vacancies from different employers, and not just integrators and *tech ))

Answer 1

Commercial unix had two pillars:
1. Manufacturer support, which linux did not have for a long time;
2. Sharpness and because of this (hello iPhones) high performance on "their" hardware.
Now linuxes with support are like uncut dogs, and the performance of "just a server" under linux is no worse, if not better, than that of very branded hardware. And the price of special systems is high, higher than that of the banal x64. All sorts of sparc, power pc and other superdromes and even mainframe are losing markets. There is no demand for them.
Hence the lack of demand for engineers. In fact, now diesel fuels and other chpuks are already illiquid, which is expensive to maintain and easier and cheaper to decide and throw away (replace with linux or free).

Answer 2

They pay for support. Nothing changed.
Only everything goes to Linux.
FreeBSD, Solaris - losing shares.

Answer 3

solar is cool. If there is something to keep on it ... take the opportunity.
