I know more folks are chiming in, some head scratchers as well. The techies and engineers should be impressed with the current iteration of pedaled machines and the innovations.
The ever improving technology of bicycles kinda reminds me of modern motorcycles,especially the innovations from BMW. From frame materials and design, to drivetrains and wheel/tire technology the bikes currently out there are as impressive.
I look at the latest drivetrain on a touring/racing bike for example...it now has 11 cogs at the wheel hub where 5 was the way it was for years.The chain is so narrow now, was already narrow with the 9 speed vintage I ride. Hydraulic disc brakes on both wheels and even electronic shifting are a available. The same option on mountain bikes and hybrids as well.
H's newest is a full monocoque carbon frame and fork, disc brakes,Shimano di2 electric shifting and an 10 speed drivetrain. Visual and technology A+

Compared to my aluminum framed 9 speed from early 2000's, it is a space shuttle vs turbo prop plane. I can keep up, but having a few more lower cogs and wider range of front chainrings makes climbing a chore more for me. I hear a chirp from her derailleur and look down to see I have no more to bail to. Good times.
The tires are bead type, often at 115psi or more and boy will they go off like a gunshot. Prior to this evolution in the 80's, race tires were tubular, tube sewed insde carcass and glued to the shallow dished rim.On hot descents hard braking and maybe a questionable glue job, the tire could roll offthe rim. BTDT.
Was so glad when that changed. Michelin and Continental have been in this market for years among others.
I saw a Campagnolo component page with Brembo brake calipers. Shimanos are brand stamped, but imagine it's a known brake builder. Magura is a big player from day one.

I still have rim brakes on both my bikes and after riding a disc bike... just like difference of a /5 and a current model...major.Rim brakes will stop you still, but under certain conditions fade quickly.
Mountain bikes now are available with 29" wheels from the long time 26". I poo-pooed them as a fad until I gave one a try recently.It was like going to a 21" dirt bike wheel over a 17".
There are some cool fat tire bikes, some now with electric motors in a few different drivelines. E-bikes take some of the excuses away as well, rent one and check them out.
Can you tell it was raining here? Sorry
