I believe that if you look at the number of musicians, using arrangers, or not, you will find that number has dwindled considerably since 1999, statistically by 41 percent. Nearly all the musicians I know have either retired, or took up another occupation since Covid destroyed what little was remaining. As for the buggy whips, they are still in use today, mainly for trotters. But, I would not expect most folks on an arranger keyboard forum to have much knowledge of that industry.
All the best,
Gary (an old geezer - and damned happy to make it this far!)
