Being in RC for years, and understanding the fundamentals is key, any yuppie can afford one of these, but the few that understand the equipment that come from RC will always have the advantage.
This is just like any other field out there. 90 percent of so called photographers can take a picture, but there's only 10 percent that are very artistic and talented enough to get ahead. This field is no different, you have the masses, and unfortunately DJI is making a bit easy to jump in, but that's the nature of the beast.
There's not much anyone can do at this point, but that's just the business. There are some very talented people out there, but I'm sorry to say it's only a matter of time before it will be mainstream. And the people that were doing well, it will be a little tougher. That's just business.
As for liability well, china ain't helping.
