In the late 1800's my grandmother was brought to the west in a wagon. She passed in 1975. As she lived her life she saw electricity move into the house, along with telephones, radios, TV's, air conditioning, forced air heating, refrigerators, gas stoves, and microwave ovens. Even home computers were starting to be introduced. Outside she saw automobiles, airplanes be introduced as well as men walking on the moon.
In my life I cannot think of many life technological introductions as I get up in years that are true life changers. We have smart phones, which we use to send pictures of cats with and text while driving. We have some noninvasive medical diagnostic devices. We have internet that is primarily used for pornography and ordering Christmas gifts. But pretty much everything is just a faster and improved version of what already existed 50 years ago. Cars are still cars, planes just fly faster and further, my TV gets Netflix but it's still a TV. But today America can't get a man into space, I will be lucky to obtain the lifespan of my grandparents, our education system vs what kids were learning a century ago is pathetic, roads and bridges take 10x longer to build, etc etc. There have been very few life changing technologies introduced in the last 50 years.
I think humanity hit a ceiling sometime around 1970.
What say you?
Progress isn't linear in general. It goes in starts and fits and sometimes a design is the best form possible for its purpose.
The wheel was invented thousands of years ago, but who has improved on a round wheel? They are made of steel or aluminum now, and attach differently than they used to but they are still round. It was the best solution, period. Until the aircraft was invented probably. But for ground travel a wheel 2000 years ago served exactly the same function as today.
Hand-canons, the precursor to pistols and muskets, were around in the 12th century. It took 500 years or more to get to a rifled barrel and a true modern rifle. Along with this, the musket ball took longer to be replaced by a cartridge and bullet.
The pace of invention and improvement in the last 150 years has skyrocketed and many of the forms of inventions has stabilized at the near-best iteration. Assault weapons for war haven't changed much at all in 60 years. The internal combustion engine also hasn't changed much in general.
So the next jumps in technology will be slower coming and will be very large jumps. We'll likely figure out plasma energy at some point in the near future. We've already 'transported' particles from one location to another. Computing power is poised to take one or more quantum leaps.
Long story short (well long story long at this point lol), there is no 'steady advance of technology and progress'. In the long run yes, but in the relative short term no.
Consider humans were making campfires 800,000 years ago at least. When was fire first used to forge metals? Or glass? A few thousand years ago.
