It's going to be normalised in the coming years, across small and huge companies. Not sure how all the web devs will adjust.
Also we aren't in 2010. You don't need to build as much in house anymore or patch up tech that doesn't scale. Modern frameworks, cloud, and open source tech makes things at least 10x easier than they used to be. We will only improve in this regard.
Only if the rate of newer services/companies keep up and outweigh the ease of development we should eventually reach. People are currently still maintaining jQuery PHP and other tech that makes doing anything much more complicated than it needs to be.
might be a naive take but i think LLMs will improve the ease with which maintenance can happen.
one of the major problems with older tech is finding people who are willing to work in that domain for cheap - LLMs seem to trivialise that.
