55-60Mbps is a reasonable expectation. Don’t get fooled by exuberant speeds advertised by the powerline equipment manufacturers.
Lag can jump by ~25msec
The premise of the article (if it can be called that) is incorrect. He made the statement about the 5 computers in a TV interview (and it was not related to business trip referred in the article).
I saw the recording of the interview some 10-15 years ago. Don’t remember which network. Perhaps NBC?
What you say doesn’t make sense at all. The article describes a shareholder meeting in 1953, when IBM was already aware that the market is much bigger. It had to happen significantly earlier, but not later than in 1940s, because the concept of programmable electronic machine (a computer, not calculator) was established only then. And they were selling a lot of calculators by then.
At that time there was no such thing as TV broadcasting casually interviewing various people.
Outside the techies and gamers circles, for the general public - it was fairly unknown.
Today it’s known primarily due to its high stock valuation.
Thus, don’t project your own bubble on everyone out there.
QNX is squeezed from above by Linux, especially as real time patches have finally been fully accepted. And from below by FreeRTOS and Zephyr.
Current attempt to open source is a desperate move by QNX as their market share is disappearing.
Why would anyone in their right mind step on the same landmine, called QNX, which already pulled a rug from under the developers feet once?
Absolutely no trust in QNX ecosystem.
Save yourself pain and aggregation. Don’t use QNX.
There are not any real time patches for Linux: there's only the low-latency kernel. Low-latency and realtime are different things. A lot of the time the two can appear superficially similar, until they don't and your airplane falls out of they sky.
The realtime executives are not operating systems. Executives and operating systems are two different things.
QNX is a realtime operating system. It addresses the niche of a realtime operating system that isn't being met by anything else out there, and has been doing so for 40 years, even if free versions for hobbyists haven't been available for many of those years. It's not about market share since that's always been there. It's about mindshare and given the comments here, that's obviously missing.
A preemptable kernel does not make Linux a realtime OS. A low-latency kernel does not make Linux a realtime OS. There are great things in their niches but when you need a realtime OS, Linux is still not going to be fit for purpose.

Are you sure they want to open source it? Is this just an assumption, or can you provide a reference?
I actually tried to find out whether the source code of the kernel etc. is included in the free version they provide, but they require to install a license manager on my machine, so I stopped; and it doesn't look as if it was open-source when there is a license manager (would be very easy to get around).
Spoken like a true Marxist. The purpose of Marxism is to literally kill hundreds of millions of people who oppose the Marxist way. Like they did during the 20th century in the countries where Marxism prevailed (even briefly).
Avoid nvidia if you can. Their attitude towards anything Open Source has been extremely unsupportive if not outright shitty. Part of company philosophy.
What to do about it - hit these oil companies, including the Saudi ones, with a huge class action law suit. Additionally US government must fine heavily instances of collusion and oligopoly so that others thinking of following path will be deterred.
