The most important aspect is motivation to improve and do cool shit. That can, also, be said about a lot of professions. The best thing you can do is to find what is most interesting to you and spend at least a few hours a week learning about it or engaging with it. It could be new features of a language you know, a programming methodology that is new to you, learning about/contributing to a FOSS project you like, or anything else.

School and work will almost definitely force you to engage with the parts of development you don’t like, as well will give you an opportunity to engage with the parts of development you do like. It’s on you to keep yourself engaged and improving in your skills.

I think part of the issue is that it does act more like a search engine crawler than a traditional user. A lot of sites rely on real human traffic for revenue (serving ads, requests to sign up for Patreon, using affiliate links, etc) that gets bypassed by these bots. Hell in some cases the people running the sites are just looking for interaction. So while there is a spike in traffic, and potentially cost, the people running these sites aren’t getting the benefit of that traffic.

Basically these have the same issues as the summaries that Google does in their search results but, potentially, have much larger impact on the host’s bandwidth
