No doubt. They have become THE most advanced drone fighting force in the world. An entire, vital industry created from the crucible of war.
This sudden drone epiphany is in some ways similar to the early 20th century, the Age of the Battleship when heavy metal naval ships were still considered the ultimate expression of power, but then the advent of aircraft as highly cost effective ship killers emerged with torpedo and dive bombers. You can build a LOT of planes and bombs/torpedoes for a fraction of the cost of producing a naval vessl. It quickly became clear that planes kill ships much better than ships do. And then the sudden rush into aircraft carriers over gunboats, if your country was rich enough to do it.
Repulse and Prince of Wales were the most advanced British warships of their day, and were sunk by Japanese aircraft in hours. Same as Yamato. There had been lots of examples prior, like Bismarck & the battle of Taranto where it became clear that relatively cheap planes - including obsolete biplanes - were able to kill VERY expensive naval captial ships. Similarly, drones have proven to be the effective counter to mechanized infantry, tanks and artillery that anti-naval aircraft were to traditional capital ships.
Drones at scale have a MUCH lower barrier to entry, and Ukraine are now the experts.

Well, we’re crossing discussion streams significantly as this point, but I’ll have a go.
Depends what you mean by “afaik the japanese wanted to surrender…”. The fanatical military leadership certainly didn’t, and wasn’t going to. After Okinawa, it seemed pretty clear what an invasion of any of the home islands would look like. And the allies were VERY concerned about countering the USSR’s advance in Europe, hence didn’t want to get bogged down in a years long bloody ground campaign in Japan. It was a higher priority to stop the russians than to do things ‘the old fashioned way’ in Japan. It’s more complex than that, of course, there wasn’t just one single reason why the U.S. used the atomic bomb.
If you want to have a moral argument about ‘demonstrating their power on defenseless civilians’, well, I’m sorry I’m not likely to move you on that.
