I went back to Web 1.0
Back around 2000 when I was fiddling about with web development, there was no real use of JavaScript worth speaking of. Us web designers were in the midst of moving to CSS-based styling (and layout, sanity permitting) and any ads that were around were text or image-based. Most of us designers even optimised any images, trying to shave off a few more bytes so that it'd load half a second faster over a 56k dial-up connection.
Move forward by twenty years, and optimising for file size as well as overall accessibility (websites that break fully without JS enabled, and do not work well with screenreaders etc. when it is) have been tossed out of the window. Want to browse the web with a dial-up modem? At blistering 2-4 kB/s, that 2 MB page (even with some cached data) is going to take ~34 seconds at an average speed of 3 kB/s. Optimistically, that's you waiting under a minute for a single page.
But who is using 56k dial-up these days, you ask? Roughly 2 million Americans, for one: https://www.dailydot.com/debug/dvd-rental-windows-3-aol-2017/
Even though I have had access to a fast broadband connection for many years now, I still do not appreciate the way that pages have bloated up, the myriad of JavaScript pop-ups and JavaScript-based ads. The JavaScript-based reloading and changing of the page while it's loading, causing the browser to re-render and re-render it multiple times, which causes the fun 'skipping around' effect one sees on pages these days.
These days I am using a non-commercial browser (Pale Moon), with JavaScript enabled per website address (NoScript) and ads fully blocked (uBlock Origin). I have tried to go back to just using the web again like I used to in the past, even with just a bit of ad-blocking to weed out the worst offenders, but the degradation in overall usability is shocking. Ironically, using glitched-out websites due to no JS and missing stacks of ads making the layout collapse is still a better user experience than the other way around.
Really makes one wonder where things will go from here. Moving the rendering engine out of the browser and into JavaScript, so that it is 'always up to date'?
