> As a young person my biggest concern with hiring old people is that exact attitude: this is just like $IRRELEVANT_OLD_TECH.

Leaving aside the (substantial) ageism issues here, it looks to me like your reading of the GP's complaint is incorrect.

It's not a judgment that $NEW_TECH is going to not catch on or otherwise fail because it's just like $NOW_IRRELEVANT_OLD_TECH.

It's the observation that much of the $NEW_TECH that catches on and succeeds for a time often turns out to offer approximately the same utility as $NOW_IRRELEVANT_OLD_TECH... and similar adoption costs, which we pay over and over again. We rent rather than buy.

There are counterexamples I can think of -- new tools/abstractions/practices I've adopted that have resulted in near order-of-magnitude gains. But the ratio of these to other $NEW_TECH that just sort of shuffles the dirt around... well, that probably approaches another order-of-magnitude relationship.

And there's also the argument about the aggregation of marginal gains (see Brailsford and the British cycling team); approximately the same utility isn't quite the same thing as exactly the same utility and I don't think that should be overlooked. In fact, I think one could put together a specific case that the GP is arguably not correct in making an even comparison between Powerbuilder and webapps on precisely such a basis.

Still, an aggregation of marginal gains approach only ends up helpful if the marginal and opportunity costs are low.

How often do you find that's true for $NEW_TECH over $NOW_IRRELEVANT_OLD_TECH?

And since we're being free with judgments about age here (generalizations, naturally -- not that you or I would ever let such general thinking affect our judgment when it comes to individuals)... do most young developers really have enough knowledge and experience to answer that question effectively?

Further, most people seem to have little appreciation of the difference between order-of-magnitude gains and shuffling the dirt around. Certainly, there are those who are wrong in assuming anything new is just dirt-shuffling, but for anyone without experience, everything offers an order of magnitude. And this really is an engineering discipline---$NEW_TECH is never as good as its proponents say, but it the best trade off in some circumstances, while $OLD_TECH is never as bad (or good) as the "general consensus" would have you believe, while it is almost certainly inappropriate under some scenarios.
