Well I am glad there might be some help keeping the solo up to par for a little while. But I don't expect much as new drones are coming out all the time that have surpassed what this thing is capable of no matter how much programming you want to do. I am cautiously optimistic.
If you're referring to the obstacle avoidance features becoming common on newer products, I would agree they're desirable features to have, but they really are in a totally different category than the videography features the Solo has - smart shots, easing, free-look when reflying a cable, etc. In the vast majority of situations, it's far easier for me to manually avoid obstacles than it is to totally smoothly transition framing from one shot to the next, and be able to do it repeatedly.
To use the ever popular car analogy, it would be like saying Tesla's autopilots in their cars have surpassed what an old pickup is capable of. Well, yea, if you're only talking about automation. If you want to haul 2 tons of gravel, the pickup is going to win every time, autopilot be damned.
I think people overlook what the Solo is/was. It was first and foremost, a platform for capturing high quality video clips - of which the actual framing and moves are key. The newer products are more cutting edge drones that can also capture high quality video. Each puts a different priority on given features making them better or worse in X vs. Y and vice versa.
Personally, I would still take the Solo over any other product today.
