I would go further than that. It will probably never be a problem.

The merchant is required to validate with chip if the card has a chip - the machine will prompt to use chip and pin if you try to swipe a card that has the chip. But merchant can override this if they wish. In that scenarion merchant bears the cost of fraud if it happens. Eg in England Waitrose was late out with the machines (they had internal techncal problems) and for a couple weeks, they voluntarily accepted chip cards and thus took that risk so that they would not inconvenience their customers.

If the card doesnt have a chip, the readers always have a magnetic reader as backup. And in that case the card companies do not penalise them.

Even here in Norway for example, there are banks such as Scandiabank that continue to issue cards with no chip, if the account holder wants that.

And why not? You see, it will take decades before chip and pin could be 100% standardised across technically lagging regions such as Eastern Europe, Asia, Africa, South America and......err....USA. yet the idea of a visa or mastercard is that you can go anywhere worldwide and it is accepted. So merchants in Europe will still be accepting this card even if in a few years it is 100% in use in Europe. And that is not close

So there is no reason to worry. Both will coexist for a very long time. I
