All these professions did not disappear. They have transformed though more to tending and overseeing machines, at an income level below middle class, with a much smaller number of highly-skilled professionals doing the exceptional things which machines don't do too well.
When the technology is good enough for a one person to record an entire album, it's hard to be a specialist musician, like a violinist in an orchestra, or even a guitarist in a band
I suppose the skilled professions that will resist machine replacement for longest time are these which require a lot of custom work and adjusting to unique local circumstances: electricians, plumbers, car mechanics, doctors, hairdressers, maybe construction workers. But they will likely handle mostly special cases, where standard, machine-friendly solutions don't fit well, a bit like modern tailors.
