Lol no. Sasuke has always been good, he was just anti-hero, who wanted some smacking first before getting convinced that 'power of love and friendship' are enough to bring peace to the world and better than doing it by force. Villains have always been popping out of nowhere. The technological advancements are a consequence of peace. Now with better things to do than killing each other, effort is being put into education, sciences and other things that make the world better for everyone.

You can see exactly the same things in real life. Also the technological growth isn't unbelievable. They already had technology akin to 21st century in Part 1 Naruto, it was just less common in ninja villages.
