Whether it is EA or not, there is always a time when all things will fail. I have learnt to be humble over time.
Some traders have moved on to be a broker instead.
Indeed automated or semi automated strategies playing a vital role in trade business. It's a difficult task to find which EA can work good on live accounts. EA's can help trading in a better way but mostly traders thinks EA's help them catch profits so fast and very quick growth they expecting that's why few good EA's also shows a falling results. In fact EA's doesn't means so quick growth so if a trader use EA for normal growth with low leverage obviously we can see better results.
Overall EA's purpose to help peoples who are new or they don't know how to trade other side in my opinion an expert person don't need any EA else trade panels which can help them for pasting SL/TP, catching profits etc instead to sit long on desk.
Using an EA for fast and slow growth makes big difference in results. EA's are like guiding tools to help trader like human using other machines in daily life as guiding tools.
Definitely you don't like robots :) .. If you have a 'can do' attitude, then everything is possible in coding.
I don't believe in those stats numbers, ... It doesn't matter how money are coming, ... 1x..x0% a month or 1x..x0% in a single trade, as long as they are in the equity then the job is done.
