Shimano pays people to tell you your 10 year old top-of-the-line Dura-Ace is rubbish compared to its new kit.
(it is twaddle, so I wouldn't bother watching, but there are lots and lots of bikes being trashed in the name of 'upgrades' by people who don't know why, but are influenced by such marketing nonsense)
Functionality wise, SORA R3000 shifts better than Dura Ace 7700 IMO, I'd say that Tiagra 4700 10 speed is as good as 11 speed 105 and better than Ultegra and possibly DA hidden cable 6700/7900, not sure about 6600/7800 as I missed that gen but they were the benchmark apparently and better than the first hidden cable STIs.
Brakes and chainsets, braking is impacted far more by pad/rim interface, set up, tyre pressure/tyre compound and even the rider themselves, than the calipers/levers IMO. As for chainsets, to me there's not much difference, I can still knock out over 1000 watts in spurts (which isn't that big a deal), I use a carbon chainset on my carbon bike (it matches colour wise), is there much if any difference with a stronglight 99 on my 50s Carlton when I get out the saddle and give it the beans, meh, not enough for me to be thinking I need to 'upgrade' and likely more flex in the BB area of the frame.
Bottom brackets in the last 25 years have gone backwards, the whole mess of differing standards adds to the nonsense, chose my carbon bike on the basis it was one of the last 68mm threaded made for a decent level branded bike.
I like that I've been able to buy robust bikes that are lighter than ever, make cycling easier and haven't cost the earth, being able to go touring using a machine that even with rack/guards and accoutrements is only 10kg, and has space for wide tyres to go off roading would be well beyond my budget 25 years ago.
The other thing is front lights, yes the throw is much improved, so inclement weather, night time riding can be safer, but it's the battery tech and low energy bulbs that makes it so much easier, and again at prices that are so much less expensive than 25 years ago.
One other thing, being able to put more gears in between the highest and lowest so that transitioning whether for work, touring or even a hard ride at the weekend makes riding easier.
Pedals, I actually still don't mind toe clips but for every day use I love SPD/SPD type, foot security and quick exit plus being able to have a chunky/robust shoe you can walk all day in and has brilliant comfort and support.
