The “useles eaters” analogy only comes into play if you plan on reducing society to the bare minimum: farmers, manufacturers, cops, what-have-you.
Exactly that "bare minimum" farmers, cops or whatever are constantly reduced in modern societies. From the other side, the number of bureaucrats, paper movers, financial advisers, influencers, IT and other useless crap grow.
There is nothing complex in any real work at all. "I'm calculating plane wings", "I'm building space rockets", "I'm making plastic from oil", even "I'm writing software to calculate plane wings" and so on will be perfectly understandable for any person. Real things have a real application, so it is easy to explain what you are doing if you could anchor in final result. Useless job needs a lot of "professional" words because there are even no real application of the result. So, useless employee have to not only describe his job with the strange words, but also think out some lie about why people need that crap he doing. There is nowhere to anchor in explanations, so they are either weird, or endless, looped like uroboros explanations.
Of course, computer programming, system administration and computer science isn't useless. That thing named IT nowdays is mostly useless. The result you could easily see literally right now. Take a look how much memory and CPU/GPU your browser eating just to show page you are reading now with simple text and some images.
It’s really not as simple as that : modern farming techniques and automation made being a farmer mostly useless, as evidenced by higher crop yields and lower numbers of farmers. However it made farming equipment mechanics and engineers more useful; it made farming equipment sales managers more useful; it freed up labor to be allocated elsewhere (or in a free market sense, more incentive to do something other than farm made it profitable to do so).
But that is not what happening in reality. In reality farmers are obliged to buy seeds from "approved" sources, forced to pay for "vaccinations", forced by machinery manufacturers to vendor lock without having a right to repair and so on.
Mechanics are got rid because they can't repair vendor locked machinery, engineers can't apply their skills without tons of senseless regulations, even agronomists losing jobs, because there is nothing to manage on strictly controlled by government farm where some legislative papers dictate you what exactly you should sow and where and seeds manufacturers that force you to follow their guidelines to be allowed to buy seeds next year. You can't breed your own
varieties of plants anymore. Even fertilisers are strictly regulated. There is nothing to do for agronomist any more on a farm.
But at the same time, the army of law enforces and supervisors from government and corporate sector is growing with insane speed. Even lawyers are breeding in enormous amounts to help corporations to sue you for "unapproved" repair or keeping your own seeds.
Technology bring a lot to a farmers, and if we lived in some another world, things could be as you describe. But in our world, technology was hijacked by greedy elites obsessed with idea of total control over humanity. So, no, when farmer buy a new tractor, it is not a new regular service job for village mechanic, it is a village mechanic starvation, along with more money farmer have to spent on service and repairs, because new tractor could be repaired and serviced only on authorized corporation service station only with corporation spare parts and only as expensive modules. And farmer have to pay them full price for whole diesel high pressure fuel pump instead of a single valve piston or even just a small gasket.

By that standard IT isn't useless
Of course, computer programming, system administration and computer science isn't useless. That thing named IT nowdays is mostly useless. The result you could easily see literally right now.

You're just confused about what IT is. System administration and anything having to with networking is IT
Excellent observation

So you can't explain your job
